Abstract
PURPOSE: To obtain a joined part free from generation of voids by heating the surfaces to be joined of ≥2 base materials at above their eutectic temp. in an atmosphere contg. a large amt. of O2 thereby forming a melt phase and an oxide phase on the contact surfaces of the base materials.
CONSTITUTION: Two or more base materials, for example, Al and Cu are placed in an atmosphere contg. O2 of an amt. larger than that in the atmospheric air, more particularly, an atmosphere consisting substantially of pure oxygen. Next, with the O2 held introduced into the contact faces of the base materials, the base materials are heated to the temp. range above the eutectic temp. thereof and at which the base materials do not melt. As a result, the O2 intruded into the clearances of the base materials and the components in the base materials are caused to reacted so that the oxide phase formed thereby is diffused into the melt produced by eutectic reaction. Therefore, the remaining of the O2 intruded in the clearances of the base materials as voids in the joined part is prevented. Here, said melt phase may be expelled from the contact faces by pressurizing the base materials or may be left as it is on the contact faces without being expelled.
