DEVELOPMENT OF TEXTURE DETERMINATION METHOD FOR THE NEAR-SURFACE-LAYERS

A method is described which allows to estimate of texture for near-sur face layers, especially useful in analysis of texture inhomogeneity. T he method is based on so called mono-layer pole figures, which are mea sured with keeping of the information depth by means of omega- and chi -tilting of the sample. Mathematical relation between the goniometer a ngles {omega, chi, phi} and pole figure angles {alpha, beta} is given. The mono-layer pole figures for stacked aluminium sample with changed rolling direction in uppermost layer, were measured.
