【摘要】：研究了低碳高强钢在不同淬火和回火温度下的显微组织和力学性能。结果表明,随淬火温度升高,强度呈现先升后降的趋势,冲击功先缓慢增长再急剧下降;随着回火温度升高,强度逐渐降低,冲击功逐渐增大。当淬火温度为900℃、回火温度为500℃时,回火屈氏体细小致密,碳化物均匀分布,钢的综合力学性能较好。
[Abstract]:The microstructure and mechanical properties of low carbon high strength steel at different quenching and tempering temperatures were studied. The results show that with the increase of quenching temperature, the strength increases first and then decreases, the impact work increases slowly and then decreases sharply, and with the increase of tempering temperature, the strength decreases and the impact work increases. When the quenching temperature is 900 鈩，
