Parameters of Mechanical Properties and Resistance of Intermetallic Compounds to Martensite Transformations

Abstract:

The paper analyzes Poisson’s ratios μ₀=μ_100,001=-s₁₂/s₁₁ and elastic anisotropy factor A'=s/s₁₁ (s=s₁₁-s₁₂-s₄₄/2) for single crystal materials of binary and three-component TiNi-TiFe alloys with gradually deteriorating resistance first to one B2-R and further to two martensite transformations B2-R-B19'. The study discusses a ratio H/E of TiNi-TiFe alloys both subject and not exposed to martensite transformations. Surprisingly, this ratio exceeds 0.035 for alloys with martensite transformations, being far higher than in the majority of metals and alloys.
