  • Patent number: 6074500
    Abstract: A method for producing a metal component which is made up of at least two partial elements with differing material properties is distinguished in that a first partial element made of a steel material, which can be tempered, is preassembled in a recess in a second partial element made of a magnetic iron material of low retentivity. A copper based solder is applied to the preassembled component at the recess in the transition area between the first partial element and the second partial element. Thereafter, the component is heated to a temperature which lies above the melting temperature of the solder. After the liquid solder has been distributed in a contact area of the two partial elements, the component is cooled. The component is then brought at least once to the tempering temperature of the steel material of the first partial element, is maintained at this temperature for a predetermined length of time and then is completely cooled.
