The technique of simultaneous investigation of the laws of occurrence and development of rotational and translational modes in situ during plastic deformation of the samples

Abstract

The described technique, allowing in situ in the process of plastic deformation of samples at the same time monitor the emergence and development of translational and rotational modes. The first method uses a technique of producing color cards orientation and imaging them colors. In the second - the effect of laser diffraction on quasi-periodic deformation relief in the form of slide steps. The color orientation maps allow to determine the characteristics of the substructure with a linear resolution ~ 1 micron and angular ~ 10 seconds.

Using the laser technique makes it possible is to follow the emergence and development of sliding and determine characteristics such as sliding direction and its change in the deformation of the sample, the minimum distance between slip lines characterizing the intensity of slip and slip lines degree of curvature that characterizes the strengthening investigated sample.
