Understanding the Stress-Induced Movement of γ /ϵ Interfaces and Coalescence of ϵ Martensite Variants Through Fractal Analysis

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