The multiscale modeling of materials has evolved, in recent years, from academic and research studies of Low Level of Technology Maturity (or TRL, in its acronym in English corresponding to “Technology Readiness Level”), towards its industrial application for the design and prediction of component life, as well as for the development of new materials. Thus, the methodology called “Integrated Computational Materials Engineering (ICME)” goes beyond computation and experimental model verification, by including “integration” and “engineering”. According to Horstemeyer1 the ICME establishes the bridge between two or more experimentally validated models through which information is transferred from one code to the other. In the case of the design of new metallic materials, or in the prediction of their degradation in service, the ICME methodology requires the ability to integrate the models of materials and processes with the simulation tools at different scales and with the design rules. . One of the main components of the success of an ICME methodology is, therefore, the correct integration between different scales (experiments and models) and different disciplines (materials science, engineering, design, etc.) including an intense and dedicated experimental activity.
