一种钽靶材织构评价方法的模型构建

Model Establishing of an Evaluation Method for Tantalum Target Texture

  • 摘要: 研究了一种钽靶材织构评价方法模型, 关注100、110、111三种面织构的组份含量和分布均匀性, 并对三种织构进行了定义, 规定晶界角度定义为≤2°, 组份含量取与标准织构取向差小于15°的晶粒的百分含量;同时, 对取样方法与测试方法进行了规定, 依据本模型, 可通过织构分布折线图、15°取向图和IPF图来对钽靶材单点与整靶织构分布情况进行综合评价。

     

    Abstract: The model of an evaluation method for tantalum target texture was establisheds, and component contents and distribution uniformity of 100 , 110 and 111 textures were investigated, and the grain boundary angle was decided to be no more than 2°. Texture contents were the percent of grains with the standard texture orientation deviation less than 15°. Meanwhile, sampling method and testing method were regulated. According to the model, single-point texture distribution and multipoint texture distribution could be evaluated by statistical chart, 15°orientation graph and IPF coloring map.
