Abstract

Transformation sequence and behavior in Ti45Pd45Ni10 alloy (numbers indicate at.%) have been investigated. The solution treated alloy shows reverse martensitic transformation from B19 to B2 structure, B2 to long period stacking order (LPSO) structure, LPSO to B2 structure and precipitation of Ti3(PdNi)4 and Ti2(PdNi)3 phases successively upon heating. The above transformation sequence is confirmed by electrical resistivity measurements and in situ electron diffraction experiments. The martensitic transformation is suppressed by the formation of LPSO phase. Morphology and crystallography of the LPSO phase are also discussed briefly.
