Scale Factor,Intensity of Measuring Phase State,and Peculiar Features of Atomic Volume Behavior during Martensitic Transformations in Low-Stability Alloys Based on Titanium Nickelide

The paper presents an analysis of regular features of variations in phase composition and atomic volume of the austenite and martensite phases, and the value of Bein's deformation during thermoelastic martensitic transformations versus crystallochemical factors in low-stability alloys based on titanium nickelide doped by different elements (Fe, Co, Rh, Cu, Pd, Pt, Au). It is established that the low-stability alloys undergoing different sequences of martensitic transformations (B2–B19, B2–B19, B2–R–B19) demonstrate different values and character of the atomic hopping range during transformation.
