中文摘要:以304不锈钢为实验材料,对其退火和冷轧后的性能和组织进行检测和观察,分析了冷轧变形量和退火工艺对304不锈钢组织和性能的影响。 结果表明:增大冷轧压下量,退火工艺为1100 ℃× 5 min 时获得较高的r值。
英文摘要:The microstructure and properties of 304 stainless steel as-annealed and cold-rolled were observed and measured. The influences of cold-rolling deformation and annealing process on the microstructure and properties of 304 stainless steel were analysed. The results show that higher r values are obtained by increasing cold-rolling reduction, annealing at 1100 ℃ for 5 min.
