    • Abstract
  • Based on the similar effect of WC and Mo2C addition on microstructure optimizing and wettability improvement of Ti(C,N)-based cermets, the microhardness of Ti(C,N)-based cermets with WC or Mo2C addition was investigated at high temperature. The results show that the high-temperature microhardness of Ti(C,N)-based cermets with WC and Mo2C addition both decreased with the increase of temperature. At 600-800℃, the high-temperature microhardness of cermets containing WC was slightly higher than that of cermets with Mo2C and microhardness was almost the same at 900℃. The indentation area and average indentation depth of two cermets both increased with increase of temperature. The true strain of cermets with WC was significantly less than that of cermets with Mo2C addition, but high-temperature deformations of two cermets were nearly close at 900℃.
