Study on high grade vanadium-aluminium alloy prepared by aluminothermic reaction
摘要
Abstract
High grade vanadium - aluminium alloy was prepared by aluminothermic reaction using V2O5 and Al powders as raw materials. The effects of Al content in raw materials on purity of alloy and recovery of vanadium were investigated in this study. The results show that the purity of vanadium decreases with the addition of aluminum element in raw materials and there exists a maximum value of 98. 45% when aluminum element is 5% shortfall in raw materials. The recovery rate of vanadium increases with increasing aluminum element in raw materials and there exists a maximum value of 92. 4% when aluminum element is 15% excess in raw materials. Brinell hardness of alloy comes to the minimum value of 213. 6 HB when aluminum element is 5% shortfall, and comes to the maximum value of 250 HB when aluminum element is 15% excess. The high grade vanadium - aluminium alloy with different purities can be prepared by varying the content of aluminium in raw materials.关键词
