Metal Phase Transformation
The Metal Phase Transformation interface provides a basic way to model phase transformations in metals. Six common models for phase transformations in for example steels are provided. The Leblond–Devaux, the Johnson–Mehl–Avrami–Kolmogorov (JMAK), the Kirkaldy–Venugopalan, simplified, the Microstructure based, and the Hyperbolic rate models are used to model time-dependent (diffusion-controlled) phase transformations, such as the transformation of austenite into pearlite during steel hardening. In contrast, the Koistinen–Marburger model is used to model the transformation of austenite into martensite, where the amount of undercooling below the so-called martensite start temperature controls the formation of martensite. In addition to these seven types of phase transformations, you can define your own phase transformation models and let them coexist with other active phase transformations in your analysis. You can use an arbitrary number of phase transformations in a model. The Metal Phase Transformation interface lets you generate a compound material whose properties are phase-composition-dependent. This material can be used by other physics interfaces, such as Solid Mechanics and Heat Transfer in Solids.
