✦ Synopsis

It is believed that Ti-Ni shape memory alloys can be used in fission and fusion reactor devices that may utilize shape memory capabilities. Three kinds of Ti-Ni shape memory alloy were neutron irradiated with different doses and their electrical resistance measurements were carried out after isothermal and isochronal annealing. The temperature dependence of the electrical resistance for the irradiated alloys was found to be similar to that for unirradiated alloys after annealing at a temperature of 523 K, which gives a low homologous temperature T/T,,, (where T m is the melting point) of 0.33. The results obtained from neutron-irradiated alloys are discussed, taking into account the damage generated by both irradiation and structural alterations during annealing.

A Ni-45 wt 5% Ti (Ni-50 at % Ti) alloy was cast into molds of magnesia and silica investments by use of a dental argon-arc pressure casting machine with a copper crucible. The castings exhibited shape memory properties. The shape recovery process was sharper in the specimens cast in magnesia investm

x-phase particles are precipitated when Ti is added as grain refiner to Cu-Al-Ni shape memory alloys. The size distribution of these precipitates is a function of the thermomechanical history of the alloy. The further addition of Mn to improve the alloy properties causes the appearance of a new set
