ABSTRACT

The production of master alloy from aluminium with other alloying elements such as

Ti, Sr, V etc… is a main target in aluminium industryies. The main uses of these alloys

are: in alloying, grain refining and modification. An Al-V master alloy has been

obtained by reduction of vanadium pentoxide by molten aluminium. The factors

affecting the reduction process such as bath temperature, vanadium pentoxide to

aluminium ratio and roasing temperature were studied. Some tests such as chemical

analysis, X-ray diffraction and microstructure examination were carried out on the

produced alloys. The results obtained indicate that the produced alloys containing up to

6% V in the form of Al3V can be use as a master alloy.
