The reduction partition has effect important in two-time cold rolling on Drawability of IF steel, because reduction has effect in cold rolling on {111} texture.
if钢的冷轧压下率分配对深冲性能有重要的影响，是由于冷轧过程的压下率对(111)织构的形成有影响。
The spinnability and drawability of PMMA/PET blends were studied. The orientation and crystallization structure were measured by sonic velocity method and X-ray diffraction respectively.
研究了PMMA/PET共混纤维的可纺性和拉伸性，并测定了拉伸丝的力学性能、取向和结晶结构。
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。
