Synthesis of Ti3Si0.4Al0.8C1.8 solid solution

摘要：

　　In this study,free Ti/Si/Al/C powder mixtures with molar ratio of 3∶0.4∶0.8∶1.8 were heated in Argon with various schedules,in order to reveal the possibility for the synthesis of Ti3Si0.4Al0.8C1.8 solid solution powder.X-ray diffraction (XRD) was used for the evaluation of phase identities of the powder after different treatments.Scanning electron microscopy (SEM) was used to observe the morphology of the Ti3Si0.4Al0.8C1.8 solid solution.XRD results showed that predominantly single phase samples of Ti3Si0.4Al0.8C1.8 was prepared after heating at 1400℃ for 5 min in Argon and the lattice parameters of Ti3Si0.4Al0.8C1.8 lay between those of Ti3SiC2 and Ti3AlC2.
