Effect of N2 pressure on the phase composition and morphology of Ti2AlN prepared by self-propagating combustion method

摘要：

　　Ti2AlN ceramic have been prepared by self-propagating high-temperature synthesis method using Ti,Al and TiAl mixture as raw materials under different N2 pressures.X-ray diffraction (XRD) and scanning electron microscope (SEM) have been used to determine the phase composition and micro morphology of the products.XRD analysis indicates that the main phase of the products is layered ternary compound Ti2AlN,but there are TiN and AlTi3 impurities in the products.With increasing N2 pressure,the relative content of TiN increases,whereas the relative content of AlTi3 decreases.SEM imagines exhibits that layered grains of the products become larger and tighter with increasing N2 pressures.
