Abstract
In this research, the kink band formation probability in polycrystalline LPSO single phase alloy was investigated quantitatively. First, the uniaxial compression test was performed in order to introduce the kink bands into LPSO phase. Distributions of crystal orientations in undeformed and deformed specimens were measured using SEM/EBSD. Comparing the initial distribution of crystal orientations with the deformed one, the regions where kink bands were formed were specified by Kernel Average Misorientation (KAM). From the relationship between the probability of kink band formation and the misorientation angle between neighboring grains, it was found that the probability was less than 80% even at regions with high misorientation angles.
