The objective of Integrated Computational Materials Engineering (ICME) is to better address materials R&D needs by merging modeling, experimental and data driven methods of materials sciences and engineering. Exploitation of ICME aims at discovery and development of novel material solutions, optimization and tailoring of product specific materials and overall troubleshooting of materials affiliated problems more effectively at a faster pace than traditional trial-and-error approaches. To demonstrate the application of ICME for wear and fatigue we provide an outline of in-house ICME modeling toolset and case studies focusing on design and lifetime assessment of relevant microstructures. The approach is micromechanical in nature, i.e. material features such as microstructure are tightly integrated to material properties and product requirements of practical relevance. This provides a capability to investigate material behavior in product relevant conditions by systematically developing the material solution towards increased performance in addition to seeking cost effective alternatives to meet specific product needs.
Examples from two relevant material systems are presented via case studies, martensitic steels and hard composite materials. The microstructural design of the martensitic steels plays an essential role in their suitability for different loading conditions varying from hostile wear environments in mining to fatigue engaging machine and transmission parts. Analyses of martensite microstructures with respect to fatigue and abrasive wear are presented. For hard materials imaging based modeling of material microstructure is utilized to establish causal relations between microstructure, material properties and performance under typical application environments, cases being abrasive and impact wear. Computation driven material design aspects are discussed, i.e. how to apply the respective technologies and modeling as part of product, manufacturing process and material development.
