Abstract-In this study, copper-tungsten carbide composite was produced by mechanical alloying and powder metallurgy. The effect sintering temperature and time (800°C to 1000°C and 1 to 3 h) on composite microstructure and properties were investigated. The results showed that WC is formed at lower temperature and the presence of WC favoured the enhancement of the properties of the composite. The increased both hardness and electrical conductivity has been observed with the increase sintering temperature. Index Terms-Copper-basedcomposite, mechanical alloying, sintering.

Porous metal with uniform honeycomb structure was successfully produced by sintering using Fe-Cr-Al nano powder, which was prepared by the pulsed wire evaporation (PWE) in ethanol. Its process consisted of the several steps; 1) coating on the surface of polyurethane sponge with the liquid droplets generated from the ethanol-based slurry where the Fe-Cr-Al nano powders were uniformly dispersed, 2) heat treatment of debinding to remove the polyurethane sponge and 3) sintering of the porous green body formed by Fe-Cr-Al nano powders. The strut thickness of porous Fe-Cr-Al was increased by the increase of spraying times in ESP step. Also, The shrinkages and the oxidation resistance of the sintered porous body was increased with increase of sintering temperature. The optimal sintering temperature was shown to 1450• C in views to maximize the oxidation resistance and sinterability.

“…Tribological tests have shown that the best resistance to wear have the samples after heat treatment (Fig. 16), which can be explained by the fact that after annealing recrystalization and characteristic growth of the grain do not occur, due to block in movement of the grain boundaries homogeneously distribution of alumina and formation of the third phase, identified in Lee & Kim, 2004, Anđić, 2007, Korać, 2009). This is confirmed by the microstructural examinations of the analyzed samples.…”
