title: [Mechanic-technological and metallographical studies on soldering of dental alloys].
abstract: It can be proved that the reliability of soldering is in practice not very high, as properties of solidity and the quality of compounds very greatly. This is unavoidable in spite of the most careful execution of the welding and observation of the corresponding soldering directions. Low sigmaB-values are attributable to: 1. the insufficient filling of the soldering space (ca. 80%); 2. many lacunae in the solder commissures, which partly communicate with one another; 3. small diffusion zones and poor wettability in case of the pairing of the materials Co-Cr-Mo/Au-solder.
