Constitution of the systems {Ta,Nb,V}-Sb in the Sb-rich part (> 50 at.% Sb)
Original language description
The phase diagrams of the {Ta,V}-Sb systems have been investigated by XRPD, LOM, EPMA, and DTA in closed quartz ampoules up 1050°C, and in sealed Ta crucibles up to 1450°C. The results were compared with the previously established Nb-Sb system. The result from Melnyk et al. was confirmed in this investigation since it is in very good agreement with our investigation. The following binary phases in the Ta-Sb systems: Ta3Sb, Ta5Sb4, and TaSb2 were found to be stable at 900°C. For the V-Sb system, additional binary phases are present and their mechanism of formation is different from that of the {Ta,Nb}-Sb systems. Diffusion couple experiment between V-VSb2 revealed that the following binary phases are stable at 800°C: V3Sb, V3Sb2 (ht), V7.46Sb9, and VSb2. The phase V5Sb4 previously known in the literature was found to be stable below 800°C. In contrast to the {Ta,Nb}-Sb system, only V3Sb, V3Sb2, and VSb2 were found in as cast state, which indicates peritectic formation. The other phases,
