The results showed that the if steel has better deep drawability, higher mechanical and texture strength and elongation if the hot rolling temperature was low with big reduction in ferrite region.
结果表明，较低的铁素体轧制温度和较高的铁素体区压下量时，IF钢具有更高的深冲性能、相对较高的强度、延伸率以及织构强度。
The results show that polygonal ferrite, granular bainite and larger amount of stabilized retained austenite can be obtained after hot rolling.
结果表明，热轧后能够获得多边形铁素体、粒状贝氏体和大量稳定的残留奥氏体组织。
Compared with the strip produced by conventional austenite rolling, the yield strength of the ferrite rolled strip was lower by about 20%, with same elongation and strain hardening exponent.
相对于常规奥氏体轧制，铁素体轧制薄板的屈服强度下降了20%左右，伸长率及应变硬化指数与之相当。
