Abstract
The work results of researches of crystallographic textures of constructional materials, realized in laboratory of crystal-structure researches at the Institute of Metallurgy and Мaterials Science of the Russian Academy of Sciences since last decade have been adduced. The general directions of texture analysis development, include analysis with ridge estimates and method of restoration of function of orientation distribution with approximation of mass Gaussian distribution have been considered. Efficient of using methods in supplement to researching texture of aluminium-lithium alloys has been shown. The textures features, arisen in process of plastic deformation during rolling have been shown. Their relation with crack resistance of sheet materials has been analyzed. The problem of forming system of orientable emission of strengthening phases in texture materials on the base of aluminium-lithium alloys has been discussed.
keywords
Crystallographic texture, function of orientation distribution, aluminium-lithium alloys, slipping systems, plastic deformation.
