Effect of Silicon cavbide addition on properties of compacted Ni- caproduced by powder technology

Engineering and Technology Journal, 2011, Volume 29, Issue 11, Pages 497-507

This research aimed to product Cu-Al alloys by powder metallurgy method
because of it is commercial and technological important. Copper and aluminum powders were tacking then there powders mixed and blended together and classified to four parts, Silicon carbide powder added to three parts and the last remain as its then these powders mixed and then compacted in isostatic cold pressure at 7ton, then
this compact samples were sintered in furnace under argon gas at 830°C for one hour, latest these samples grinded and polished to microstructure, density, porosity, microhardness and X-ray diffraction tests.

Increased Porosity and Their Effect on The Density and Hardness Value of (Ni—Cu) Alloy

Engineering and Technology Journal, 2011, Volume 29, Issue 1, Pages 66-74

This research is aimed to produce Ni-Cu alloys by powder metallurgy method
because its commercial and technological importance. Nickel and Copper powders
were tacked then their powders mixed and blended together and classified to four
parts, Sodium Chloride powder added (as a space holder) to three parts and the
last remain as it is then these powders mixed and then compacted in hydrostatic
pressure at 7ton, then this compact samples were sintered in furnace under argon
gas at 950°C for one hour, latest these samples are grinded and polished to
examine the microstructure, density, porosity, microhardness, X-ray diffraction
and corrosion resistance.
