ABSTRACT:
When hard-substance parts are soldered onto steel bases, thermal stresses are produced between the hard substance and the steel. These stresses can be reduced by means of using a multilayer solder in which the middle layer consists of a precipitation-hardenable copper alloy or nickel alloy provided on both sides with a layer of a hard-solder alloy whose working temperature is at least 50.degree. C. below the melting point of the precipitation-hardenable copper alloy or nickel alloy. A tempering treatment at 250.degree. to 550.degree. C. is carried out after the soldering in order to achieve a precipitation hardening of the middle layer.
