| Abstract: | After smelting Ni-Al alloy fines in a plasma are furnace, the recovered alloys with and without Al additions were investigated experimentally by means of binary phase diagrams for their chemical and phase compositions, as well as the technological effects of smelting and heat treatment processes on these alloys' properties especially on the catalysis activity of nickel framework. The results indicate that if Al addition is selected properly in combination with reasonable annealing regime taken up, the phase structure may be improved so as to enhance the catalysis activity of nickel framework. |
