Abstract
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.
