Designing of optimal structure crystallography of engineering materials

The direction of metal forming processes intensification and parts performance increase is formulated. Its essence lies in the fact that by optimizing the crystallographic orientation of the materials structure, it is possible to change the predominant development of strains during forming in favor of those directions, which will lead to an increase in the formability of blanks, the accuracy of geometric parameters and the fatigue characteristics of products. It is shown theoretical basis of designing materials with given crystallography of structure. The obtained functional interrelations allow to take into consideration material structure parameters in technological calculations of metal forming processes and, most significantly, a priori by means of calculations to determine the structure crystallography meeting the requirements of increasing the materials formability and the product performance. It is given an example of the implementation of the calculated crystallographic orientation while rolling high-strength strip from aluminum alloy 3104.
