ICME (Page 2)

Manufacturing engineers need tools that can help them understand microstructural changes during processes like welding, additive manufacturing, and heat treatment. Some available techniques (analytical, empirical, FEA) have been discussed in EWI’s recent ICME series* of papers. An additional approach uses phenomenological modeling to provide information important to predicting metallurgical behavior. EWI associates Rafael Giorjão and...

Weld thermal history, which greatly affects material microstructure especially in the heat affected zone (HAZ), can be difficult to predict accurately. As part of its ICME approach to predicting microstructural behavior in welding steels, EWI employs welding thermal cycle data -- welding parameters, materials chemical composition, joint design, and materials thickness as baseline inputs --...

Integrated computational materials engineering (ICME) principles can be applied to model thermo-mechanical material behavior in joining and additive manufacturing applications. Demonstrations and examples have been presented in several recent EWI publications.* The ICME framework can also offer a solution approach to modeling microstructural response in similar applications. EWI Principal Engineer Michael Eff and Senior Technology...
