摘要：The heat treatment of high-speed steels (HSSs) was conducted with tempering times, and the microstructure and mechanical properties were systematically investigated. Results indicated that the heated HSSs were primarily constituted by alpha-Fe, MC, M2C, M6C, and M23C6 (where M = Fe, V, Cr, etc.). As tempering time increases, the volume fraction of M23C6 increases by 25.0%, and the content of retained austenite decreases from 13.21 to 3.53 vol.%. These result in the macrohardness of HSS increasing from 58.11 HRC to 63.52 HRC and then decreasing to 57.72 HRC, and the impact toughness increases from 7.22 to 8.21 J/cm2. The impact wear results showed that, with an increment of tempering time, the wear volume loss of the heat-treated HSS decreases from 168.21 to 46.69 mm3 and then increases to 121.51 mm3. Its wear mechanism is mainly micro-cutting, supplemented by micro-fatigue.
