Abstract

The stress fields around the first butterfly martensite in an Fe-Ni based alloy were calculated. The calculation results inducate that there are tensile stress fields near the convexity and the two ends of a butterfly martensite. There is a compressive stress field near the concavity. New butterfly martensite is likely induced not only near the convexity but also probably near the concavity. The butterfly martensites induced in tensile stress fields are bigger than those in compressive stress fields. The second butterfly martensite is likely induced near the convexity within 2πm region. All these results agree with the experimental observation.
