METHOD FOR DETERMINATION OF CRYSTALLOGRAPHIC ORIENTATION OF GRAINS ON SURFACE OF POLYCRYSTALLINE SAMPLE

摘要

Method for determination of crystallographic orientation of grains on surface of polycrystalline sample relates to physics of solid body, engineering of physical experiment. Subject of the invention is in fact that to flat surface of poly-crystal that for reveal of relief is previously affected by chemical etching one directs flux of white light. By means of digital device on basis of light-sensitive matrix one registers light dispersed by surface and as color orientation map one transfers it to computer where through comparison of parameters of color of each grain to parameters of colors of grains from compiled previously data base color-direction one automatically determines crystallographic orientation for all the grains on radiated surface simultaneously. Technical result: simultaneous obtaining of information on orientation of all the grains on radiated surface, decrease of labor consumption of the process.
