METHOD OF JOINING FIRST MEMBER MADE OF ALUMINIDE-BASED INTER-METALLIC COMPOUND AND SECOND MEMBER MADE OF METAL

摘要

PROBLEM TO BE SOLVED: To provide a method of joining by which a temperature drop in joining and a decease in joining time are realized by using an aluminum foil which has a low melting point and is available at a low cost. SOLUTION: An aluminum foil 9 is inserted between the face 7 to be joined of a first member 5 composed of an aluminide-based inter-metallic compound NiAl and the face 8 to be joined of a second member 6 composed of a metallic material Ni, and then both members 5 and 6 together with the aluminum foil 9 are heated and the aluminum foil 9 is melted during the heating process up to the joining temperature. After that, both members 5 and 6 and molten metal liquid are kept at the joining temperature and then solidified isothermally.
