説明
It was recently found by the present authors that, when WC-βt-Co alloy (βt=WC/TiC/TaC s.s.) was sintered by using Co powder and βt powder supersaturated with WC (named βt(E) powder), sheet-like WC phases crystallized in the structure during sintering. The βt(E)-Co mixed powder was sintered and then hot-pressed to get anisotropic WC-βt-8mass%Co alloy specimens having the stratified structure of sheet-like WC. Some properties such as mechanical properties, cutring performance, etc. of the above alloy were investigated.<BR>The sheet of WC, its surface orientation being coincided with (0001) planes of WC, became parallel to the specimen surface perpendicular to the hot-pressing direction with increasing reduction in thickness. The surface hardness and transverse-rupture strength of specimen were higher than those of usually isotropic alloy. The crack propagation across the sheet-like WC was greatly checked. The edge strength of cutting tools was improved considerably. The phenomena above mentioned were discussed in detail.
