ABSTRACT:
Disclosed is a method of jointing a member of Ti-Al alloy which mainly consists of an intermetallic compound, TiAl, and a member of structural steel. The jointing uses an intermediate member made of an austenitic stainless steel or a heat resistant steel, or a Ni-based or Co-based superalloy, between the above two members, and the jointing of the intermediate member and the structural steel member at least is carried out by friction welding. A typical example of the jointed machine part manufactured by this method is an engine valve.
