The Generalisation and Refinement of the Vector Method for the Texture Analysis of Polycrystalline Materials

Abstract

A so-called “Vector Method” for the texture analysis of cubic materials was presented for the first time at this conference in 1976. Since then this method has been refined and applied successfully to non cubic-materials. It is shown in this paper that the Vector Method provides several advantages over series methods of texture analysis, the most important of which being the relatively small amount of experimental data which are needed for the determination of the entire crystallite orientation distribution.

EFFECT OF CRYSTALLOGRAPHIC AND MORPHOLOGIC TEXTURES ON THE ANISOTROPY OF MECHANICAL PROPERTIES OF Al-Li ALLOYS

“…The crystallographic texture was measu red by X-Ray diffraction and analysed using the lrectorial method [5]. The results of these measures are presented in details in another communication at this conference [6].…”

X-ray diffraction

“…Although the APD is rarely modified for texture analysis, specialized equipment of a similar nature with computer control is employed. The vector method of texture analysis is now being used to analyze the data and is described by Ruer and Baro (351) and Ruer et al (352). Matthies (353) discusses the reproducibility of the orientation distribution function obtained from pole figure measurements.…”

The feasibility of the reproduction of the texture function by the vector method

“…However, as has already pointed out, the relationship between pole figures and the ODF does not necessarily lead to the above-mentioned limitation of the reproducibility of the ODF if one adopts as a basis a discrete orientation space, as is the case in the vector method (Ruer, 1976;Ruer & Baro, 1977 a, b;Ruer, Vadon & Baro, 1980).…”
