Influence of different heat treatment processes on micro-structure and properties of high strength low alloy steel
Abstract To improve the strength and toughness of high strength low alloy steel, conventional quenching and tampering, bainite austempering, quenching&partitioning were conducted. The mechanical properties of the high strength low alloy steel obtained from each of the above heat treatment processes were analyzed through the evolution of microstructure. The results indicated that, compared with the quenching & tempering and bainite austempering process, toughness value was improved by 24~26% through quenching & partitioning process. Meanwhile, the tensile and yield strength value decreased slightly. The improvement in properties is related to the different decomposition amounts of austenite.
