Abstract

Different mechanisms of plastic straining and recovery bring about specific changes in the geometry of grains. Two parameters quantifying those changes are introduced. They allow to study the contribution of mechanisms of plastic deformation in a wide range of temperatures. An application example of the geometrical measurements is given. Measurements of the changes in geometry of grains in an austenitic stainless steel enables to detect the temperature range where grain boundary sliding and grain boundary recovery significantly contribute to the total strain of the material.

Keywords : grain size, mechanisms of plastic deformation, shape of grains
