A method to improve the machinability of titanium and titanium alloys, and titanium alloys with good machinability.

摘要

PURPOSE: To improve the machinability of pure Ti or Ti alloy while maintaining hot workability and high fatigue strength or corrosion resistance. ;CONSTITUTION: P is blended by 0.01-1.0% together with 0.01-1.0% S and/or 0.01-2.0% Ni, and the improvement of machinability is attained by means of the embrittlement of matrix and by the formation of fine inclusions of proper shape. Further, 0.01-5.0% REM can be blended together with P, S, and Ni.;COPYRIGHT: (C)1993,JPO&Japio
