Apparent morphologies of coarse plate martensite

Abstract

The apparent morphologies of coarse martensite plates were researched in detail in this paper. It was found that coarse plate martensite may appear as parallel to each other, or packet, or 60° angular, or equilateral triangular, or equilateral hexagonal morphologies. Moreover, traditional ideal believing the orientation of martensite to be a chaotic and random distribution was analyzed, and showing that any martensite will combine regularly together along the habit plane pursuant to a definite pattern, hence the regular distribution of martensitic plates in space should be a spontaneous tendency. Other viewpoints concerning plate martensite were also discussed.
