采用精确的线材织构测定方法与取向分布函数(ODF)相结合的方法研究了不同热处理制度下冷拔珠光体钢丝中织构演变的变化规律.帘线钢盘条首先经过1223 K保温0.5 h后空冷至室温,然后在296、773、923 K3个温度下进行0.5 h的等温处理,经冷拔后获得试验样品.研究结果表明:冷拔珠光体钢丝帘线中晶粒取向主要集中在α取向线上,形成＜110＞>丝织构.主要织构组分为{001}＜110＞、{111}＜110＞、{110}＜110＞,其中{001}＜110＞织构组分的强度最大.反极图定量计算表明:296 K时,＜110＞织构组分的体积分数由表及里呈现上升趋势;而773 K时,＜110＞织构组分的体积分数由表及里先下降后升高;923 K时,＜110＞织构组分的体积分数由表及里先下降后升高,在中心层达到最大.
