Neutron Diffraction Texture Analysis of 1 Vol.% Cu in Aluminium

Abstract

Neutron diffraction texture determination was carried out in two-phase composites, AlCu1%, prepared by powder metallurgical methods and extruded 84 and 89% respectively. The texture of the minor Cu-phase can be measured with a sufficient degree of accuracy within reasonable time. This texture is weaker than the texture of the Al-matrix phase corresponding to the lower internal deformation degree of the former one. It is estimated that the method can be extended to even lower volume fractions of the second phase.
