Heterogeneous Combustion of Ti/Si/C Powders with Estimated Ti₃SiC₂ Routes Morphologies

Abstract:

In this study, about 62.2 wt% Ti₃SiC₂ was synthesized via tungsten inert gas (TIG) welding method, as potential in advanced material applications. This arced sample was characterized using XRD and FESEM analysis to observe the phase presence, and its morphology. Ti₃SiC₂ phase favours to form at 5 s and produces elongated platelets (Ti₃SiC₂) grain, micro-porous equiaxed (TiC) grain and melt regions (Ti-Si), when observed at the dense surfaces. Meanwhile, fine dendrite, quasi-spherical, and pyramidal grains were observed at the pore sites. The laminate dendrite of Ti₃SiC₂ was estimated to form at the origin of TiC faced pyramidal crystal, which nucleated toward TiC pyramidal crystal surface at the specific angle.
