Abstract

Microstructure evolution of peritectic Al-25at.%Ni alloy during directional solidification with pulling velocity ranging from 2 to 500μm/s is investigated. The directional solidified alloy is composed of Al ₃Ni₂, Al₃Ni phase and eutectic (Al ₃Ni+Al) phase. When pulling velocity ranges from 2 to 5μm/s, Al₃Ni phase grows into an integral matrix. Majority of primary Al₃Ni₂ is consumed by peritecti reaction and transformation behind the peritectic interface with pulling velocity ranging from 2 to 20 μm/s. While pulling rate increases, major Al₃Ni phase direct solidifies from liquid. With cooling rate increasing, Al ₃Ni₂ phase content firstly decreases and then increases, while the Al₃Ni phase content decreases throughout.
