[ 1 ] - بررسی عوامل موثر بر سختی و چقرمگی شکست هاردمتال‌های کاربیدتنگستن-کبالت

Mechanical properties of hard metals are very close to starting material, carbide grain size, kind of binders and sintering temperatures. In this research, effect of the amount of binder phase, starting powder and sintering situation on the mechanical properties of hardness and fracture toughness of Tungsten carbide-Cobalt hard metals were investigated. The results showed that the powder granul...
