摘　　要：冷轧深冲钢(即IF钢)的成形性能是其冲压加工时保证零件质量最重要的因素。通过静态拉伸、织构分析、成形极限等试验方法,分别研究了IF钢的基本成形性能和模拟成形性能。试验结果表明:IF钢具有优异的力学性能、高的延伸率、高的应变硬化指数、高的塑性应变比以及低的平面各向异性度。此外,IF钢的成形极限较高,深冲及复杂变形时有较高的安全裕度。The formability of cold-rolled deep-drawing steel （IF steel） is considered to be the most im-portant factor in its stamping process to ensure the quality of machine parts .The basic formability and simulating formability of IF steel is studied by the static tensile test ,texture and forming limit test .The results show that IF steel has excellent mechanical properties ,high elongation ,strain hardening exponent （n-value） ,plastic strain ratio （r-value） and low degree of planar anisotropy .In addition ,IF steel has high level of the forming limit with high safety margin in the case of deep drawing and complex deformation .
