摘要
采用铝热还原法制备了钒铝合金,研究了原料配比对钒铝合金微观形貌的影响,采用激光粒度分析、扫描电子显微技术对原料粒度和铝钒合金进行了分析。研究结果表明:当物料质量比Al∶V2O5为1.02时,V2O5还原率可以达到97.20%;随着Al粉的减少,产品内部孔洞逐渐变小,形貌更加均匀。
Vanadium aluminum alloy was prepared by thermite reduction method.Effect of raw materials ratio on the micro-morphology of vanadium-aluminum alloy was investigated.The particle size of raw materials and V-Al alloy were analyzed by laser particle size analysis and scanning electron microscopy.The results show that when the mass ratio of materials of Al:V2O5 is 1.02,the reduction rate of V2O5 is as high as 97.20%;with the decrease of Al powder,the inner holes of the product become smaller and the morphology is more uniform.
