Abstract
A TiNi shape-memory alloy was experimentally manufactured by the vacuum hot pressing method, using pure titanium and nickel powders. The homogeneity and density of the TiNi alloy obtained by this method varies according to the temperature and pressure applied during vacuum hot pressing as well as the holding time. The results of studies of mechanical and physical properties confirmed that the alloys obtained show extremely effective shape-memory characteristics. Thus, it was demonstrated that the TiNi shape-memory alloys can indeed also be produced by the vacuum hot pressing method using elemental titanium and nickel powders.
