| Abstract: | The WC-Co cemented carbide was prepared by powder technology with argon gas pressing and sintering at 5 MPa.In order to investigate the effect of carbon content,sintering parameter,cobalt content,nickel content and ball milling parameter on the transverse rupture strength(TRS) and density of the alloy,the experiment was arranged with Shainin's variables search experiment design.It shows that the effect sequence from high to low on the transverse rupture strength is the interaction between sintering paramete... |
| Keywords: | WC-Co cemented carbide coarse grain transverse rupture strength relative density variables search experiment design |
