LOW STRENGTH AND HIGH DUCTILE TI ALLOY FOR COLD WORKING

摘要

PURPOSE:To reduce the tensile strength, to increase the ductility and to improve the cold workability of the title Ti alloy by specifying Sn and/or Zr, Mo and Ti. CONSTITUTION:In the case of contg. Mo, Sn and Zr, the Ti alloy is formed with the compsn. consisting of, by weight, 6-18% Mo, 0.3-8% Sn+Zr and the balance Ti. In the case of contg. Mo and Sn, it is furthermore formed with 6-18% Mo, 0.5-10% Sn and the balance Ti. In the case of contg. Mo and Zr, it is moreover formed with 6-12% Mo, 0.5-10% Zr and the balance Ti.
