Quantitative analysis of compatible microstructure by electron backscatter diffraction

Abstract

We propose a scheme for assigning the martensite variant using electron backscatter diffraction in a martensite material that undergoes a solid–solid phase transformation. Based on the solutions of the crystallographic equations of martensite, we provide an algorithm to assign martensite variants to a particular microscopic region, and to check the elastic compatibility of the microstructure corresponding to low hysteresis and high reversibility in shape memory alloys.
