TI-NI形状記憶合金鋳造材のDSCによるマルテンサイト温度の評価

抄録

The effect of cold rolling on martensitic transformation temperature in cast Ti-50.5at%Ni shape memory alloy from self-propagating high temperature synthesis (SHS) ingot were studied. Shape memory alloy specimens were casted by lost-wax process from SHS ingot. The microstructural feature was analyzed by scanning electron microscopy (SEM). The elemental contents were analyzed Energy Dispersive X-ray Spectrometry (EDX). The structure was analyzed X-ray Diffraction (XRD). The heat treatment and the change of the transformation temperature by the rolling conditions were measured by differential scanning calorimetry (DSC).
