An attempt has been made to correlate shape memory behavior and the micromechanical characteristics of the martensite crystals in the polycrystalline microstructure of thermally and thermomechanically processed nearly equi-atomic Ni–Ti shape memory alloy. The nanoindentation measurements have shown that suitable schedule of thermo mechanical treatment improves the hardness of the martensite phase. The recovery index parameter (η) obtained from the load–depth profile illustrates the recovery of the indentation strain of the martensite phase.
