The microstructure of stress-induced martensite and its evolution in a Ti36
Ni49Hf15 alloy have been investigated by TEM techniques. And the reasons fo
r no stress plateau in the tensile stress-strain curve of the Ti36Ni49Hf15
alloy deformed in an austenite state have also been discussed. (C) 2001 Act
