| Abstract: | A new type of low alloy and high strength,high toughness and wear resistance steel was developed by multielement alloying and modifying heat treatment The basic characteristics, microstructure, fracture morphology of the steel, as well as the effect of heat treatment on mechanical properties and wear resistance of the steel were studied The results show that the stability of undercooled austenite of the steel is higher, which makes the steel possess high hardenability The tempering stablility of the steel is better too After quenching at 880920 and tempering at 250300 ,the steel has obtained tempered lath martensite and possesses high strength, high toughness and high wear resistance |
