The emerging field of temperature dependent electro-chemo-mechanics of solids brings the opportunity to gain novel, energy-efficient, environmentally-friendly, less costly synthesis and processing routes for inorganic materials. External electric and magnetic fields affect solid-state diffusion processes and offer an additional degree of freedom to tailor microstructures and properties:

  • Synthesis and phase formation by solid-state reactions and diffusive phase transformations
  • Densification of particle-based materials and microstructure coarsening (pore elimination and grain growth)
  • Mechanical deformation (plasticity and creep)

The presentation of experimental work, including in-situ characterization, as well as modeling and simulations is encouraged in order to provide a rational, comprehensive knowledge for intentionally using electromagnetic energy to manipulate matter in metals, intermetallics, oxide and non-oxide ceramics as bulk, thin or thick films.

Additive Manufacturing (AM) technology has been pointed as the next industrial revolution. Starting from prototyping of plastic parts and currently available for the production of metal components, extensive R&D activities are still necessary in order to push the technology into maturity levels for its industrialization. 
For the last, improvements covering the whole manufacturing chain must be developed, including quality standards, implementation of processes for raw material and process monitoring, AM design, modelling of residual stresses, thermal treatments, finishing processes, non-destructive testing, among others. Also, metal fabrication by additive manufacturing places strong challenges towards the materials science and engineering community. Therefore, major emphasis is being placed on the understanding of the role of materials in metal based AM processes with regards to microstructure, residual stresses, defects and the quality of the powder. 
In the framework of this symposium, the current state of the art and future trends for the industrialization of AM and materials will be discussed.

This symposium addresses recent developments in thin films for structural and functional applications covering their synthesis and preparation routes, advanced microstructure characterization,  exploration of microstructure-property relationships and their applications in surface engineering. Both fundamental and application-oriented contributions are solicited. 
Three major areas are in the focus of the symposium: 

  1. Thin films and surface engineering devoted to structural applications especially to wear protection and friction reduction in tools, components and other tribological systems. For instance, improvement of coating's performance with respect to high thermal stability, oxidation resistance and adhesion, optimum mechanical properties and lower friction, high potential for enhancement of tool and components performance. Presentations on progress in fundamental understanding of novel multi-component, metastable solid solutions and nano-structured coatings, on advanced coating architectures and design concepts and on large scale deposition approaches are highly welcomed.
  2. Microstructure engineering of metallic and ceramic thin films to create novel micro- and nanocomposites: this includes metallurgical processes controlling the microstructure evolution in micro- and nanoscaled thin films (e.g. diffusion or  interface related phenomena such as grain growth and phase transformations); novel processing routes harnessing the metallurgy to tailor the microstructure (e.g. utilization of pulsed thermal treatments to vary the morphology of composites or to facilitate the formation of metastable microstructures); influence of microstructure design, processing and post-treatments on properties and residual stress state.
  3. Transparent conducting oxide (TCO) and functional thin films for light and heat management: vacuum, wet and combined processes and their maturity in industrial applications, enhancement of properties by heat treatment with traditional as well as new methods, including laser-, plasma-, microwave- or IR-heating, new processes, like e.g., aerosol deposition, ALD and PLD. 

The symposium will include two special sessions: 

  • Session dedicated to the memory of Prof. Dr. rer. nat. Monika Willert-Porada.
  • CREATe-Network session with invited speakers working on the EU-Marie-Sklodowska Curie funded cooperation project (2015- 2018).

This session solicits contributions on the relationships between materials combination, interface structure, microstructure and properties of nanocomposite and nanolaminated functional inorganic coatings. Together with appropriate materials selection, advanced nanostructured coatings can be synthesized from various physical or chemical routes by designing their microstructure and architecture at the nanoscale. The general prospects are to advance functional coatings (nitrides, oxides, metal and semi-conductors) with tailored superlative properties -superhardness, toughness, ultrawear-resistance, increased thermal or chemical stability, radiation tolerance, controlled friction etc. This session emphasizes synthesis, in-depth characterization (e.g., STEM, atom probe tomography, nano-diffraction, design strategies, properties, and applications of such coatings. Papers dealing with atomistic/multiscale modeling of surface/interface properties are also greatly encouraged

Precise control of materials interface and surface is a key enabling technology for enhanced performance in microelectronics, optics, photovoltaics, biomedical implants, etc. Especially moving from 2D to 3D surfaces with a well-defined and engineered thin-film composition, homogeneity, conformality as well as ease of fabrication is a paradigm shift in materials integration. Atomic Layer Deposition (ALD), Atomic Layer Etching (ALEt) and related technologies enable a precise thin-film control for a steadily increasing demand of materials and materials combinations. Fundamental studies are needed to provide the necessary understanding for advancing in this growing field and be able to fully implement it in current and future applications. Precursor chemistry, deposition speed and cost remain the target of most research and development efforts. This symposium will target current trends and advances in Atomic Layer Deposition and related technologies with special emphasis on their application in microelectronics, optics, biomaterials and energy generation and storage.

Materials synthesis based on the use of molecular precursors has been recognized as a powerful way to access compounds with controlled and adjustable compositions, crystal structures, morphologies and consequently property profiles. Thus, a careful design of suitable molecular precursors as well as an extensive knowledge about their (thermal) conversion into desired functional materials are of crucial importance for providing improved rational preparative concepts towards tailor-made (multi)functional structures. Molecular synthesis techniques towards functional materials are highly attractive, as they can be performed with highly efficient atom economy, they allow access to well defined chemical and phase compositions as well as to unique morphologies and (metastable) phases. 

The aim of the symposium is to present concepts for the synthesis of novel multifunctional materials with a tailor-made nanoscaled structure. The focus lies in presenting new concepts and designing matter from atomistic to macroscopic scales through chemical materials technologies. Processing of a large number of materials with controlled crystal structure, porosity and dimensionality involve a significant interplay of process design and chemical parameters, which is rarely considered as a guiding parameter. The present symposium will critically consider various aspects related to the synthesis of functional materials from molecular precursors. Within this context, the precursors chemistry related to gas-phase and solution preparative approaches such as chemical vapor deposition, solvothermal synthesis, sol-gel processing, preceramic polymers-based methods, etc., will be addressed in detail. Moreover, fundamentals related to the conversion of the molecular precursors into (multi)functional materials will be extensively considered. Specific emphasis will be put on the intimate correlation between the molecular architecture of the precursors and the structural features and properties of the resulting functional materials. Moreover, aspects related to novel molecular synthesis strategies, mechanistic elucidation of the conversion of the molecular precursors into improved functional materials as well as to the integration of the resulting materials into structures and devices for various applications such as sensing, energy conversion and storage, theranostics, etc., will also be part of this symposium.

Traditional methods used for fabricating multi-material components show limitations when advanced materials are involved with large parts and complex shapes to be joined. These limitations can be overcome by novel fabrication processes and by new joining materials, together with suitable surface engineering. Such processes are enabling the fabrication and utilization of components for high temperature structural applications in energy, environment, transportation, and aerospace. Joining and integration include: adhesives, brazing, glass sealing, diffusion bonding, transient liquid phase bonding, and surface engineering. 
Reliable methods to test joint strength will also be part of this symposium.

Proposed session topics:

  • Joining of multimaterials
  • Joining at the nano- and micro-scales
  • Design and modeling of joints and interfaces
  • Mechanical tests of joined components

Strain hardening, creation of residual stress profiles and evolution of damage are the three major material reactions related to metal forming processes. So far, damage mechanisms are not quantitatively considered when metal forming processes are designed to manufacture parts of desired structural performance. However, control of damage during metal forming would offer the potential of an improved  structural performance, finally leading to lightweight components. Damage control during metal forming can only be achieved if the damage initiation and accumulation mechanisms can be quantitatively characterized, and simulation approaches are established that allow to predict and evaluate these phenomena. The symposium, therefore, aims to highlight recent scientific developments in the field of damage mechanics guided design of metal forming processes, modelling of damage initiation and accumulation mechanisms during cold and hot forming, and characterisation of microstructural damage mechanisms in 2D and 3D.

The deposition of thin films at glancing angles, either by evaporation or magnetron sputtering, has emerged during the last years as an invaluable methodology for the fabrication of nanostructured and sculptured thin films and multilayers with unique properties and high prospects of use in sectors such as photovoltaics, sensors, biomaterials, batteries, fuel cells and several others. This symposium aims at providing an up to date account of the last advances made in the field during the last years by bringing together physicists, chemists, engineers and other specialists incorporating this deposition approach for the nanostructuring of thin films during growth. Experimental and theoretical papers are called regarding fundamental and application issues of the methodology including its physical principles, the effect of other processing parameters besides geometry in the properties of the films, their outstanding optical, electrical and mechanical properties or the technological and industrial implications of their use. The possibilities of introducing geometrical control approaches in other processes and deposition techniques (e.g., plasma, laser, ion assisted deposition, etc.) will be also addressed.
