固溶处理后的2组304不锈钢样品分别经应变量ε=2的多向锻造(MF)和单向轧制(DR)后,再经900℃高温退火2-120 min.采用电子背散射衍射(EBSD)技术和五参数晶界面分析方法(FPA),研究了样品的晶界特征分布(GBCD)和晶界面分布(GBPD).结果表明,2组样品中∑3n(n=1,2,3)特殊晶界的比例均不超过45%,并且在退火过程中,非共格∑3晶界逐渐共格化,Σ9和∑27晶界比例也随之下降.分别经MF和DR处理后再经120 min退火的样品中,一般大角度晶界(过滤掉Σ3n)一般均以〈111〉扭转晶界和〈110〉倾侧晶界为主,表明样品中均存在明显的晶界织构(GBT);在某些特定取向差条件下,一般大角度晶界的GBPD在样品中存在显著差异,表明退火之前的加工过程对304不锈钢的GBPD有显著影响.
