Effect of TiC whisker addition on properties of YG10F alloy

摘要：

The cemented carbide material (YG10F) with different additions of TiC whisker (0％,0.3％,0.6％,mass fraction) was prepared by different techniques.The effect of TiC whisker addition on the density,microhardness and toughness of the experimental material was investigated.The results indicate that after the wet-milling for 8 h and sintering in vacuum at 1 440 ℃,the toughness of YG10F is remarkably improved and meanwhile higher microhardness is obtained by 0.3％ TiC whisker addition.Preliminary analysis suggests that the main toughening mechanism of TiC whisker in YG10F is whisker pull-out and bridging phenomena.
