ICME Methodology to design of metallic materials

24 May 2023

“Two case studies are presented: hydrogen embrittlement of steel and additive manufacturing of aluminium alloys”

ICME methodology develops metallic materials, capable of withstanding more extreme operating and manufacturing conditions

The ICME methodology addresses the complex interactions between the chemical composition of materials and the intrinsic features of their manufacturing process, and the resulting microstructure, which conditions the material properties and performance of the component.

This methodology enables the development of new metallic materials, capable of withstanding much more extreme operating and manufacturing conditions, due to the emergence of disruptive applications and radically innovative manufacturing processes.

Case studies: hydrogen embrittlement of steel, and additive manufacturing of aluminium alloys

In the case of hydrogen, the ICME methodology assesses the influence of H2 on the fracture risk of the material and the suitability of various microstructures to reduce hydrogen diffusion, as well as determining the chemical composition and manufacturing conditions necessary to achieve the microstructures of interest.

For the additive manufacturing of aluminium alloys, the ICME methodology evaluates the influence of chemical composition and process conditions on the resulting microstructure, as well as the influence of the latter on the mechanical properties; facilitating the design of new alloys that are specifically adapted to the characteristics of additive manufacturing.

ICME (Integrated Computational Materials Engineering) is developed in the Elkartek programme with partners IMH, BCAM, CEITUPV/EHU, Mondragon Goi Eskola Politeknikoa and TECNALIA.
