Abstract:
Irradiation of a crystalline solid solution can cause the decomposition of the matrix into enhanced, modified thermal, or irradiation-induced precipitate phases. Irradiation can also transform the matrix into a new crystalline phase. Alternatively, the heavily irradiated matrix can become amorphous. Alloys of NiTi are intermetallic compounds with shape-memory applications whose amorphization is of both technological and basic scientific interest. Our purpose is to observe some details of the intermediate stages of amorphization to provide further insight into the mechanisms of the phenomenon. An alloy of 50.5 at.% Ni/49.5% Ti was obtained from Raychem Co. as 0.76-mm- thick sheet and then rolled to 0.5 mm sheet. Disks 3 mm in diameter were punched and annealed for 0.5 h at 850°C. This results in an ordered austenitic (B2) structure, which partially transforms to martensite after air quenching.
