method for improving the machinability of titanium and titanium alloys, and titanium alloys with good machinability.

摘要

The machinability of titanium or a titanium alloy is improved without adversely affecting the hot workability and fatigue strength or corrosion resistance by addition of P: 0.01 - 1.0% along with one or both of S: 0.01 - 1.0% and Ni: 0.01 - 2.0%, or along with S: 0.01 - 1.0%, Ni: 0.01 - 2.0%, and REM: 0.01 - 5.0%, on a weight basis.
