ABSTRACT:
A nickel-titanium-palladium based alloy for converting heat energy into mechanical energy. The alloy exhibits shape memory. The alloy contains palladium to raise the temperature at which the alloy flexes between a deformed condition at a relatively colder temperature and a nondeformed condition at a relatively higher temperature. The alloy is characterized by including boron for increasing the fabricability of the alloy.
