抄録

The effect of thermal cycling and aging on the transformation behaviors and the microstructure in martensite of Ti-50.0 at%Pd alloy has been investigated by differential scanning calorimeter (DSC) and transmission electron microscopy (TEM). There is no change in Af temperature upon thermal cycling in spite of the increase of volume fraction of {101} compound twinning and the dislocation density. The aging treatment was subjected just below the As temperature. Af temperature of the aged alloys slightly increases with increasing aging period. Twinning modes in martensite in the aged specimen are essentially the same as those of the solution treated one. However, a large number of stacking faults on the (001)B19 basal plane is induced upon aging.
