摘要

This paper adopted quenching and partitioning (Q&P) with different annealing temperatures to a Fe-0.3C-5Mn-1.0Al alloy, and investigated the microstructure–mechanical properties relationship by optical microscope, scanning electron microscope, x-ray diffraction, tensile test and friction test. Compared with the samples treated at 600/720/780 °C, the sample at 660 °C exhibited ferrite and high-content austenite microstructure, and had 934 MPa ultimate tensile strength and 43% elongation. In addition, the friction coefficient at 660 °C is lower than those of the samples at 600 and 720 °C. It should be noted that although the initial martensite content and hardness of the experimental sample at 660 °C were not high, the final wear resistance was good, which was related to the enhanced transformation-induced plasticity effect during the friction test. Therefore, the Q&P treatment is a novel way to improve, the wear resistance of medium-Mn steels by affecting the retained austenite content.
