<i>In situ</i>observation of grain boundary migration by synchrotron radiation topography

Abstract

The application of in situ synchrotron radiation (SR) transmission topography to the study of grain boundary migration in bicrystals of an Fe–6 at.%Si alloy is described. The details on experimental arrangement of the high-temperature in situ observations of dynamic processes in material are given. The pertinence of this method is documented by comparison of the data on migration of {130} grain boundary measured this way and by optical method after heating and cooling cycles.
