I want to simulate the plasticity for the Ti and its alloys with two phases (Alpha and Beta) in Abaqus. Now I have already created the microstructure model but unsure what properties I should assign to its two constituent phases, namely alpha and beta, as I only know the bulk material parameters (e.g., Ti-10Mn)?
Alpha and beta are part of Ti-8Mn; the only difference I see is that one will be HCP while the other the BCC structure, so how do I create such a material?
Dear Ayush Kumar Jaiswal
I assume you are using some kind of crystal plasticity model.
You can find parameters for the alpha phase here:

and see the crystal plasticity implementation here:

In crystal plasticity, you will need to use two different material models for the two phases. Normally in Abaqus you would define two different user materials and assign them to the different grains representing different phases (sections of the geometry).
