Abstract
Tungsten alloys was synthesized by self propagating high-temperature synthesis (SHS) from two different reactants systems of FeWO4-Ni-Al and Fe2O3-WO3-Ni-Al. The reaction was carried out in a SHS reactor under static argon gas at the pressure of 0.5 MPa. The standard Gibbs energy minimization method was used to calculate the equilibrium composition of the reacting species. The reactants mixture was activated by high energy milling for 1 hour. The effect of the difference of starting materials to the result products were investigated and discussed. The products were characterized by inductively coupled plasma-optical emission spectroscopy (ICP-OES) and scanning electron microscope (SEM) with energy dispersive x-ray (EDX) technique.
