Voronoi Diagram-Based Microstructure Modeling and Micromechanical Analysis of Quenched C35 Steel

In this work, austenite–martensite transformation in a low alloy steel is modeled using Voronoi algorithm. The evolved fraction of martensite predicted from the geometry diagram constructed, incorporating nucleation kinetics and obtained results are validated against Koistinen–Marburger equation. geometrical properties phase identified characteristics Poisson–Voronoi diagram. Finally, microstructure developed used to analyze local stress–strain behavior different phases microscale. Results show that higher stress values distributed strain austenite phase.
