Abstract
An ion‐irradiation‐induced phase transformation from Ni2Al3 to NiAl has been investigated by transmission electron diffraction. Compound samples of Ni2Al3 were irradiated at liquid nitrogen, room temperature, and 100 °C with 300‐keV Xe and 60‐keV Ne ions. Transformation to NiAl was observed in all cases. Detailed examination of the closely related equilibrium NiAl and Ni2Al3 structures permits explanation of this transformation based on the structural similarity of the two phases and using a model built around radiation disordering of vacancies.This publication has 15 references indexed in Scilit:
