Porous NiTi alloy prepared from elemental powder sintering

  title={Porous NiTi alloy prepared from elemental powder sintering},
  author={B. Li and Li-jian Rong and Yi-yi Li},
An elemental powder sintering (EPS) technique has been developed for the synthesis of porous NiTi alloy, in which Ni and Ti powders are used as the reactants and TiH2 powder is added as a pore-forming agent and active agent. Effects of various experimental parameters (sintering temperature, sintering time, and TiH2 content) on the porosity, pore size and pore distribution as well as phase composition in experimental alloys are investigated. It is found that in order to avoid the formation of… CONTINUE READING
