Introduction Nickel-base alloy is an attractive alloy in industries for its high corrosion resistance and high strength[1-5]. However, its adhesive wear resistance is not so high [6-10]. Therefore.... Micro-strain in nickel-base alloy is stronger than that cobalt-base alloy. There are not obvious imperfects in the weld. Hardness in cobalt-base alloy is more than 390HV and the major carbides in cobalt......
Oxygen and Nitrogen Effects on MC Carbide in K465 Nickel-Base Superalloy () 摘要:Effects of oxygen and nitrogen on MC carbide in nickel-base superalloy K465 were investigated, because neither of the two gas elements was found to decide MC carbide morphology monotonically. The morphology of MC carbide under alloy solidified in conventional investment casting condition was observed to transform......
