ZrB-(O～60)％Zr和TiB-(0～60)％Ti硬质合金是用活化法(自动传送,高温,合成)制备的,并在合金加压后测其挠曲耐压强度和硬度。以ZrB_2-30％zr和TiB-45％Ti合金的强度最高,其横向断裂强度分别为52和120kg/mm~2,而耐压强度分别为235和310kg/mm~2;而同一含量的粘结合金的强度比zrP~2-Zr低得多,硬度稍高于TiB-Ti(例如
ZrB- (O-60)% Zr and TiB- (0-60%) Ti cemented carbides are prepared by an activation method (automatic transfer, high temperature, synthesis) and the flexural compressive strength And hardness. The tensile strength of ZrB_2-30% Zr and TiB-45% Ti alloy is the highest, the transverse rupture strength is 52 and 120kg / mm ~ 2 respectively, while the compressive strength is 235 and 310kg / mm ~ 2 respectively. The strength of the bonding gold is much lower than that of zrP ~ 2-Zr and the hardness is slightly higher than that of TiB-Ti
