Model Establishing of an Evaluation Method for Tantalum Target Texture

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.
