The Role of H-Phase in Thermal Hysteresis and Shape Memory Properties in Ni&sub(50)Ti&sub(30)Hf&sub(20) Alloy / A.V.Shuitcev, R.N.Vasin, [et al.] // Scripta Materialia [Electronic resource]. – 2023. – Vol.230. – P.115391. – URL: https://doi.org/10.1016/j.scriptamat.2023.115391. – Bibliogr.:21.

Ni50Ti30Hf20 high temperature shape memory alloy was aged at 550 °C for 10 h and 450 °C for 50 h which corresponds to the peak hardening state with equal gain in strength caused by different size/volume fraction ratio of nano-precipitation of H-phase. In order to determine the effect of such structures on the martensitic transformation, thermal cycling and shape-memory properties were measured. It is shown that finer precipitates with higher volume fraction provide superior dimensional stability, good thermal cycling stability and small transformation hysteresis.
