) and transmission electronic microscope (TEM). The experimental results show that long-rang order recovers rapidly when annealing temperature is below 250 ℃ and changes slowly at 350-550 ℃, and then it increases rapidly at 750 ℃. The grain size of nanocrystallites of Ni3Al keeps stable and crystal defects recover when they are annealed below 550 ℃. The grains grow normally in low temperature annealing......
