冷轧变形率为70%～90%

冷轧板经1000℃退火。利用光学显微镜、X-射线衍射仪(XRD)和万能拉伸试验机研究了冷轧变形率对Cr22Mo钢组织、织构和力学性能的影响。结果显示

冷轧压下率的增大显著改善了Cr22Mo钢冷轧退火薄板的成形性能。

Abstract

The tested and studied steel Cr22Mo (/% ： 0.005C

0.012 0N) is produced by 90 t BOF-VOD-LF-200 mm slab casting-hot rolling to 5.0 mm plate-annealing and cold rolling to 1.5 ~ 0.5 mm sheet with cold rolling reduction 70% ~ 90%

and the cold-rolled sheet is annealed at 1 000 °C. The effect of cold rolling reduction on structure

texture and mechanical properties of steel Cr22Mo is studied by optical microscope

X-ray diffractometer (XRD) and universal tensile testing machine. The results show that with increasing cold rolling reduction the structure of cold-rolled and cold-rolled-annealed sheet is finer

the intensity of recrystallized texture {111}increases

average plastic strain ratio r value increases and the plane anisotropy △r decreases

and the increase of cold rolling reduction markedly improves the fbimability of cold-rolled annealed sheet of steel Cr22Mo.
