1) super-fine and high-strength IF steel
高强细晶IF钢
2) fine grain high-strength IF steel
细晶高强IF钢
1.
The fine grain high-strength IF steel is got by refinement of the grain, increasing strength of the grain boundary, restraining the secondly working brittle, no adding the dissolution element which i.
本文中细晶高强IF钢通过细化晶粒,在提高晶界强度、抑制二次加工脆化的同时,不添加使表面质量变差的固溶元素,利用独特的微细析出物沉淀强化,使其获得了优良的深冲成形性和低屈强比。
2.
This paper is based on the study of fine grain high-strength IF steel.
本文以细晶高强IF钢为研究对象,以东北大学重点实验室φ450轧机轧制的热轧板为原料,采用φ160二辊可逆式轧机进行冷轧实验、SX2-10型箱式电阻炉模拟罩式退火实验,并进行显微组织观察和力学性能测试。
