| Abstract: | Through bainite short-time isothermal quenching, the steel gain martensite,bainite and little austenite triphase composite construction. The composite construction can make 30CrMnSiNi2A have fine strength-toughness. In bainite short-time isothermal quenching, the better score of hold time is defined through studying the same mechanical properties by using variable time of isothermal quenching experiment method. |
