Understanding the Stress-Induced Movement of $$\gamma /\epsilon $$ Interfaces and Coalescence of $$\epsilon $$ Martensite Variants Through Fractal Analysis

Abstract

AbstractThe influence of stress/strain on the movement/rearrangement of $$\gamma /\epsilon $$ γ / ϵ interfaces and the coalescence of $$\epsilon $$ ϵ plates under a fixed location of a high Mn steel have been investigated through fractal measurement of $$\epsilon $$ ϵ plates. Image texture analysis has also been implemented to recognize the stored energy and configurational stability of such plates under $$\gamma $$ γ matrix as a function of tensile deformation. Fractality of $$\epsilon $$ ϵ variants are correlated with their geometrical configurations at different directions with systematic increment of tensile strain.
