Abstract

(Ti + Hf)₃Ni₄ particles precipitate in Ni-rich TiNiHf alloys aged at 823 K. The results show that the transformation temperatures of the alloys and their stability during thermal cycling increase noticeably because the (Ti + Hf)₃Ni₄ particles strengthen the matrix. In addition, the martensite variants are preferentially oriented in the 823 K/5 h aged Ti_29.4Ni_50.6Hf₂₀ alloy.
