Magnetism Study of WC-Co Cemented Carbides刘寿荣摘 要:<正> The experimental regularity and the mechanism of affecting the specific saturation magnetization(4πσ)of WC-Co cemented carbides were studied by varying alloy composition(W and C)and quenching treat-ment.The carbon effect was mainly discussed.The results show that there is no strict linear......
below 10%, the graded composite behaves essentially like an elastic solid[19], and there is no plastic deformation. The cobalt content was less than 10%, therefore plastic deformation of WC-Co cemented... of cobalt-gradient structure in WC-Co hard alloy[J]. Journal of Materials Science, 2004, 39: 4397-4399.

The results......
]. Therefore, research on ultrafine-grained and nanocrystalline WC-Co cemented carbides has become one of the hot issues in the field of high-performance hard materials over the last decade. The main application of the ultrafine-grained WC-Co cemented carbides is the production of micro-drills and routers for printed circuit board (PCB), which can promote the development of many industrial......
on the modified linear elastic fracture mechanics approach. Good agreement between the estimated and experimental fatigue lifetimes was confirmed. Key words: WC-Co cemented carbides; fatigue lifetime; crack growth rate; stress intensity factor 1 Introduction WC-Co cemented carbides have been widely used for cutting tools, die tools, and machine parts because they have excellent wear resistance superior......
