【Abstract】 In this paper. Cr12MoV steel was treated by means of technology of prequenching-isothermic treatment, quenching directly and isothermal quenching treatment. The structures and the properties were analyzed and measured by means of optical metallograph, electric micre-analysis and X-rays diffraction. We have put forward that the useful way improving strength-toughness is to fine the structure of M+B_下+A’+K.更多还原
