Abstract

Powder mixtures corresponding to the compositions V33.3Si66.7, V25Si50(SiC)25and V20Si60C20(at. %) were mechanically alloyed starting from elemental vanadium, silicon and carbon as well as silicon carbide powders. The alloying process was monitored by X-ray diffraction and thermal analysis. It was found that the intermetallic compound VSi2and a VSi2-SiC composite with homogeneous and nanocrystalline structure were obtained by high energy ball milling. The opposite effect of SiC and C on the reactions between vanadium and silicon was discussed. The annealing behaviour of mechanically alloyed powders was studied by differential thermal analysis. The fast diffusion of silicon atoms into the vanadium matrix is suggested to control the solid state reactions between V and Si in the annealing processes. © 1995.
