In this paper, Cu-based composites were prepared by the powder metallurgy method with spark plasma sintering (SPS) technique using WC (tungsten carbide) particles as reinforcing phase and Cu matrix. The effect of temperature on electrical mechanical properties was investigated, variation in content investigated at optimum temperature. microstructure 5 wt. % WC/Cu different temperatures 850 °C d...

The effect of grapheme-nanosheets (GNs) on the mechanical properties and microstructure S390 HSS alloy was investigating. sample reinforced with 0.25, 0.5, 0.75 wt.% GNS. Powder metallurgy technique used to prepare all samples. elemental powders were milled in a planetary ball mill by 10:1 powder ratio speed 350 rpm for 48 hours, mixed warm compacted uni-axial press at 550?C under 500 MPa then ...

Abstract Synthesis of Fe-Cr-Al alloy by powder metallurgy method was developed to produce a bioimplant material with low modulus elasticity. Microstructure characterization and phase identification were carried out support the development bone implant research. The alloys synthesized elemental composition 16 Cr (wt%) that added Al in variations 3, 6, 10 (wt%). synthesis an exceptional combinati...

In the last decade, titanium metal matrix composites (TMCs) have received considerable attention thanks to their interesting properties as a consequence of the clear interface between the matrix and the reinforcing phases formed. In this work, TMCs with 30 vol % of B₄C are consolidated by hot pressing. This technique is a powder metallurgy rapid process. Incorporation of the intermetallic to th...

In this research work, Al 1wt% silver coated multi wall carbon nanotube (MWCNT) composite have been processed using powder metallurgy technique. In order to distribute CNT uniformly in the aluminum matrix high energy ball milling is required. . It was found that excessive milling can lead to carbide and alumina formation. So to reduce the milling time, the surface of CNT is modified by coating ...
