Effect of Change in the Wavelengths of Short Wave Shifts on the Formation of a Twin Structure Fragment in Thin Lamellar α-Martensite Crystals

Abstract

One of the possible scenarios of the formation of transformation twins in α-martensite crystals of thin lamellar morphology typical of Fe–Ni–С alloys with low γ–α martensitic transition beginning temperatures is discussed within the framework of dynamic theory. It has been shown that the sharply pronounced inhomogeneity observed in a twin structure fragment at matched velocities of propagation with respect to short s waves and long ℓ waves is explained by the change in the length of s waves.
