Stainless steel powders (303L, 304L, 310L and 316L) were formed into tensile test bars using the “press and sinter”process. Most processing parameters, except heating rate, were kept constant. During the heating of the experimental specimensfrom

It was found that the addition of a liquid forming powder (up to 6 wt.% of a gas-atomized tin powder) to 316L powdercould activate the sintering process. Sintering activation could be observed by an increase of the sintered density and selected mecha

CuO powder is widely used because of its high activity and selectivity in oxidation/reduction reactions. CuO nanoparticles are interesting because of their high ratio of surface area to mass, which is expected to enhance the catalytic performance of
