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 \(\gamma /\epsilon \) $\gamma /ϵ$ 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 \(\gamma \) $\gamma$ 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.
