Metallurgical Phases
When you model phase transformations in a material, each transformation defines how a source phase transforms into a destination phase as a function of time. When you create a metallurgical phase node, you have to define its initial phase fraction. This is the value from which the phase fraction evolves during the analysis.
You have the option, at the physics interface level, to compute effective thermal, electromagnetic, and mechanical properties for the compound material. If you have opted to do this, you also need to define the corresponding properties of each phase. At each phase node, you can choose to create a component-level phase material. This material can be populated with properties that define the behavior of the phase. As an alternative, you can use imported material properties. This is described in

.
The phase material properties are averaged (phase-fraction averaged) into effective material properties of a compound material that can be used in other physics interfaces. This is described in
