Abstract:
A method for producing a metal component which is made up of at least two partial elements with differing material properties, comprising:forming a first one of the two partial elements from a steel material that is capable of being tempered;forming a second one of the two partial elements from a magnetic iron material of low retentivity;creating a recess in the second partial element;preassembling the component by insertion of the first partial element into the recess in the second partial element;applying a copper based solder to the preassembled component in a transition area between the first partial element and the second partial element;thereafter heating the component to a temperature above a melting temperature of the solder for distributing the solder; andcooling the component after the liquid solder has been distributed in a contact area of the two partial elements and then bringing the component at least once to a tempering temperature of the steel material of the first partial element and maintaining the component at this temperature for a length of time sufficient to solidly connect said two partial elements and to temper said steel material before completely cooling the component.
