Phase transformation in oil-quenched Ni-21.2Al-20Fe alloy

▶ In this study, the phase transformation characteristics of the quenched Ni-Al-Fe alloys have been described by internal friction measurements and DSC experiments. ▶ The effects of Fe addition on the phase transformation and internal friction behavior of Ni-Al-based alloys were investigated and discussed. ▶ The internal friction peak during heating is originated from the L10 → γ transformation. ▶ The adding of Fe has influences on the peak temperature and height.
