This article reports new experimental results on the mechanical behavior of the Ni48.9Ti51.1 alloy under shock-wave loading in the temperature range from 213 to 413 K. The samples of NiTi alloy were loaded by impacts of aluminum flyer plates with a thickness of 0.4 mm and an impact velocity of 630{+-}50 m/s. The increase in the yield strength from 0.4 to 2.7 GPa and the spall strength from 1.75 to 3.75 GPa Results indicate that in the range 213 K to 413 K, all values of the spall strength are higher than the values of austenitic NiTi alloys with high contents of nickel. The relationship Us-up for martensitic NiTi demonstrated no anomaly that was observed with austenitic NiTi alloys.
