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......
