| 摘 要： | 用取向分布函数（ＯＤＦ）方法对造成ＩＦ钢板与ＳＰＣＥ钢板ｒ差异的织构因素进行了分析。结果指出，由于铁素体中间隙原子存在状态不同经冷轧后冷轧织构不同，进而经退火后退火织构不同，ＩＦ钢的退火织构以｛１１１｝＜１１０＞、｛１１１｝＜１１２＞织构为主，ＳＰＣＥ钢的退火织构以｛００１｝＜１１０＞织构为主。｛１１１｝取向晶粒的ｒ大于｛００１｝取向晶粒的ｒ值，因而超深冲ＩＦ钢有比深冲ＳＰＣＥ钢板高的ｒ值。

| Abstract: | By means of ODP (Orientation Distribution Punction) analysis, the texturehas been investigated for the differenee of r value between deep-drawing SPCE steel sheetand eatradeep drawing IF steel sheet. According to the experimental results, owing to thedifferenee of interstitial atom state in ferrite, the cold rolling texture, thereafter, theanneaiing texture of iP sthel sheet are different from that of SPCE steel shieet. Thedominant texrure of iF steel sheet is {111}<110>, {111}<112>. The dominanttexture of SPCE steel sheet is {001}<110>. The r vaiue of {111} oricntation grain ishigher than that of {001} oricntation grain. So, the r value of IF steel sheet is higherthan that of SPCE steel sheet. |
