| Abstract: | The mining cemented carbide was regenerated by lowpressure HIP. The results show the increase in the fransverse rupture strength and the decrease in the porosity(to A00). The service life of the regenerated cemented carbide is similar to that of conventional cemented carbide. The mechanism of the denisfication of lowpressure HIP is analysed. |
