Recovery of orientation distribution function of MA2-1hp magnesium alloy exposed to equal-channel angular pressing

Аннотация

The problem of the recovery of the orientation distribution function (ODF) of a magnesium sample according to the approximation by circular normal distributions is considered. Initial data represent incomplete unnormalized X-ray pole figures (PFs). The choice of the procedure is related to its possible application for materials with the low symmetry of the sample, unique solution in the chosen class of functions, and measurement error stability of pole figures.
