Abstract

Based on the relationship between quantified blurring degree of Kikuchi bands obtained by an electron backscattering diffraction (EBSD) technique and macroscopic strains measured by a strain gauge, the local compression strain SEBSD in sinter ore has been evaluated. There is a good linear relationship between the average of SEBSD (denoted by SAVE) and the strain measured by a strain gauge (SMEAS).
SAVE=1.9SMEAS
From the variation of SEBSD on the distance from the grain boundary, the local strain is found to be mainly distributed in the volume near grain boundaries. It has been confirmed that the local strain SEBSD evaluated by EBSD patterns can be used as an index of local strains.
