Method for the Determination of Hard Alloys’ Maximum Performance Temperature in the Context of the Metal-Cutting Tools’ Usage Quality Estimation Technique

Abstract:

The article seals with the study of hard alloy (WC-Co) crack resistance (fracture toughness), depending on the temperature. Three representatives of one-carbide hard alloys (WC 94% Co 6% (fine grain); WC 92%, Co 8%; and WC 85%, Co 15% alloys) were chosen to determine the temperature influence on the stress intensity factor. During the obtained dependences’ analysis, we revealed that the hard alloy maximum performance temperature could be determined by the maximum value of stress intensity factor K_IC. The relation between the temperature of hard alloy (WC-Co) maximum crack resistance (fracture toughness) and the temperature of these materials’ maximum performance, is shown here as a result of experimental study of the dependence of impact resistance from temperature. In addition, the hard alloys’ maximum performance temperature determination technique is developed.
