Grain size effect on the structural parameters of the stress induced epsilonhcp: martensite in iron-based shape memory alloy

Grain size effect on the structural parameters of the stress induced epsilonhcp: martensite in iron-based shape memory alloy

The aim of this work was to study the effect of austenitic grain size (GS) reduction on the structural parameters of the epsilonhcp - martensite in stainless shape memory alloy (SMA). Rietveld refinement data showed an expansion in c-axis and a reduction in a and b-axis with thermo-mechanical cycles...
