摘要：
The influence of neutron irradiation on the amorphous Ti40.7Hf9.5Ni44.8Cu5 and Ti50Ni25Cu25 thin ribbons, their crystallization behaviour and martensitic transformations that occur after crystallization have been studied. The critical fluence value of 1.10(19) cm(-2) was found. If the fluence was 1.10(19) cm(-2) or less, the crystallization parameters and the temperatures of the martensitic transformation that took place alloy after crystallization hardly changed. Otherwise, a huge increase in the crystallization temperature and enthalpy occurred and the degradation of the martensitic transformation in crystallized samples was observed. (C) 2019 Elsevier B.V.
