摘要
本文根据扫描电镜图象研究了钢板表面粗化的机制,用平底凸模胀形做成形试验。测试了钢板在不同应变状态与变形程度特别是极限状态下的表面粗糙度,并用划痕毛料考察了表面局部缺陷对变形失稳的影响。
Surface roughening mechanism of steel sheets was investigated with SEM.Forming test wasperformed by a flat bottomed punch.Roughness was measured in different strain state and level,especially in limit condition.The effect of local surface defect on strain instability was examinedexperimentally with scraped blank.
