1-17. (canceled)
A method for producing a titanium alloy part comprising:
- step (A) of providing a shaped titanium alloy part;
- step (B) of subjecting the shaped titanium alloy part to a shot peening using a first shot medium;
- and
- step (C) of mechanically or physically removing at least a part of a modified layer created in a surface region of the shaped titanium alloy part as a result of step (B).
