Abstract
A process is disclosed for producing an aluminum or an aluminum alloy sintering, comprising successive steps of maintaining a rare gas atmosphere inside a sintering furnace while heating a compact of aluminum particles or aluminum alloy particles, together with a magnesium source; reducing the pressure inside the sintering furnace while heating further for thereby sublimating magnesium nitrogen to generate Mg.sub.3 N.sub.2 and bringing the generated Mg.sub.3 N.sub.2 into contact with Al.sub.2 O.sub.3 in the surface of the compact for the reduction of Al.sub.2 O.sub.3, thereby effecting heating and sintering at a temperature lower than the melting point of aluminum. The process increases the bonding strength of the aluminum alloy particles while fully taking the advantage of a sintering process. Thus, it enables aluminum sinterings or aluminum-alloy sinterings improved in yield point, strength, and elongation.
