Modeling precipitation kinetics in multicomponent alloys during deformation

A new mean-field modeling tool is developed to correctly tackle the problem of precipitation during deformation. The model an extension a previously Langer–Schwartz–Kampmann–Wagner approach for multicomponent alloys. latter now integrated together with Thermo-Calc software and physically based equations describing evolution dislocation density hot-working. New nucleation barrier critical size have also been added simulate early stages precipitation. applied hot compression tests, which experimental information was available. shows importance accounting overall kinetics, not only constant values precipitate volume fraction or size, investigate mechanical property evolution. This due complex interplay between defects precipitates’ driven by competition thermodynamics kinetics. Finally, it highlighted how strain rate used affects final microstructure material.
