摘　　要：本文概述了微合金中碳钢的主要特点,它是以消除中碳钢调质处理为目标的新型节能钢材。文中探讨了强韧化机理:分析了微量元素V、Nb、Ti等的作用规律;提出改善韧性的主要措施。本文论述了高韧性非调质钢Mn-V-N系的研制,展望了应用前景。This paper is summed up the character of microalloyed medium carbon steels. It is a new patten steels of economize onenergy. There is no need for thermal refining of medium carbon steel. This paper is progressing with tentative analysis of toughening mechanism of microalloyed medium carbon steels. Make a study of effect of microelement Nb, V, Ti, N e.t. Make a study of that improve method of toughness, develop new hight toughness steel in microalloyed medium carbon steels.
