【摘要】 本文就国内首次研究锻造用非调质钢的试验提出报告。试验结果及与之相吻合的强度计算都表明,微量钒有显著的强化作用,而改变锰含量可作为调整强度的主要手段。根据课题要求,所推荐的新钢号40MnV 正火后,具有高强度和高韧性,可与45钢调质性能相比美。更多还原

【Abstract】 This paper deals with a non-hardened and tempered microalloyed steel 40MnV.The experiment results and corresponding strength calculation show that the trace vanadium has a strong strengthen- ing effect and the manganese is a major strengthener in this microalloyed steel.The normalized products of steel 40MnV steel is nearly equal to the hardened and tempered steel 45 in strength and toughness.更多还原
