PURPOSE: To directly weld and join an Ni-Ti alloy member having a shape memory characteristic and superelastic characteristic and a different kinds of metal member. ;CONSTITUTION: This joint part consists of the Ni-Ti alloy consisting of the hot forged structure obtd. by reaction melting and pressurizing of the Ni-Ti alloy and the different metal exclusive of this alloy by melting of at least one metal in contact with the joint boundary of both metals in this joint boundary part, the hot forged structure of the Ni-Ti alloy obtd. by softening the alloy at a high temp. and pressurizing the metal on the Ni-Ti alloy side holding the above-mentioned structure and the hot forged structure of the above- mentioned different metal obtd. by softening the different metal at a high temp. and pressurizing the melt on the different metal side and the different kinds of metal. This direct joining method is provided to obtain the above-mentioned joint part. The Ni-Ti alloy member and the different metallic member are joined with high strength without deteriorating the characteristics.;COPYRIGHT: (C)1993,JPO&Japio
