Abstract
PURPOSE:To manufacture a highly efficient Ti-Ni shape memory alloy having high density and minimal in oxygen content, by filling a powder mixture consisting of Ti, Ni, and TiH2 into a metallic cylindrical body, heating the above while sucking and evacuating the inside, and then applying extrusion or forging to the above cylindrical body. CONSTITUTION:TIH2 powder is mixed by 0.2-10wt.% with a powdery raw material composed principally of Ti powder and Ni powder. The resulting Ti-Ni-TiH2 powder mixture 4 is filled, in the above state or after compacted, into a metallic cylindrical body 1 in which one end is closed. Subsequently, while sucking and evacuating the inside from another end via a pipe 2 by means of an exhaust pump 3, the metallic cylindrical body is heated to 800-1,200 deg.C. Then, after the generation of hydrogen gas is finished, another end is hermetically sealed. This hermetically sealed metallic cylindrical body 1 is subjected to extrusion or forging in the above heated state, and then, the above metallic cylindrical body 1 is removed. By this method, the Ti-Ni shape memory alloy having high density, uniform composition, and superior shape memory effect, minimal in oxygen content, and excellent in plastic workability and fatigue characteristics can be obtained.
