How can i simulate various microstructres(pearlite,martensite,ferrite etc) in abaqus?

PROBLEM
A question is put where microstructres that are found in for example tool steels can be used to analyze local stifness's and local stresses during heat treatment and mechanical loads.
The task is to evaluate and suggest a method of analyzing the effect of microstructure.`
