Quantitative comparison of measured crystallographic texture

Abstract

A new approach for the determination of a quantitative measure to compare pole figures for different specimens is presented. The suggested approach is based on the Kolmogorov–Smirnov test. A new quantitative similarity measure between the textures of different specimens is suggested. This measure is verified by means of numerical models for both cubic and hexagonal crystalline symmetry, and it is applied to real experimental data for railway wheel steel. A comparison between the existing RP value and the introduced KSP value is presented to illustrate the specific character of the latter.
