WebDec 16, 2024 · Dual-phase low-alloy steels combine a soft ferrite phase with a hard martensite phase to create desirable properties in terms of strength and ductility. Nickel additions to dual-phase low-alloy steels can increase the yield strength further and lower the transformation temperatures, allowing for microstructure refining. Determining the correct … WebNov 1, 2002 · Grain nucleation and growth are important phenomena in polycrystalline materials such as metals and most ceramics. They govern the kinetics of many phase transformations and recrystallization processes that take place during processing. The final average grain size after the transformation is directly related to the strength of the material.
WebThe first step is to verify the model predictions against analytical models of grain growth. Here, we derive the analytical model for two-grain configurations, a circular grain imbedded in a larger grain and a half loop grain imbedded in a larger grain.

In the former the microstructure evolves from state A to B (in this case the grains get larger) in a uniform manner. In the latter, the changes occur heterogeneously and specific transformed and untransformed regions may be identified.
