Abstract
Titanium-aluminum alloy is prepared as a master alloy, and the aluminum master alloy and a pure titanium material are melted by an electron beam to yield titanium alloy.
Claims14
A process for production of titanium alloy comprising:
- preparing a titanium-aluminum alloy as an aluminum master alloy,
- melting the aluminum master alloy and pure titanium material by electron beam melting to obtain a titanium alloy,
- wherein the melting is performed without using aluminum metal.
A process for production of titanium alloy comprising:
- preparing a titanium-aluminum alloy as an aluminum master alloy,
- melting the aluminum master alloy and pure titanium material by electron beam melting to obtain a titanium alloy.
- wherein the melting is performed using only the aluminum master alloy and the pure titanium material without using metal aluminum.
