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

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