Materials that are functionally graded and have a layered structure made of nickel aluminum were fabricated by powder metallurgy procedure. Al/Ni FGM consist five layers. The material sample starts with pure ends nickel. the layers (25 Ni-75Al) %, (50 Ni-50 Al) % (75 Ni-25Al) %. Samples sintered at temperature 600° C. Apparent density, green porosity, shrinkage each layer measured.

Present paper reports an overview on the processing, corrosion behavior and applications of various metal matrix composites with a special focus on iron based metal matrix nanocomposites. As iron has a much higher melting temperature compared to aluminum, copper and magnesium therefore it is synthesized using powder metallurgy technique. P/M technique is widely used because it provides microstr...

Specimens of aluminum-based composites reinforced by silicon carbide nanoparticles (Al/SiCnp) produced by powder metallurgy (PM) were anodized under voltage control in tartaric-sulfuric acid (TSA). In this work, the influence of the amount of SiCnp on the film growth during anodizing was investigated. The current density versus time response and the morphology of the porous alumina film formed ...

Aluminum matrix composites have recently taken an important role in advanced applications because they a good combination of physical and chemical properties. For this reason, work, aluminum composites, with additions ceramic particles (mullite or tungsten carbide), were manufactured order to determine the effect those on mechanical properties microstructure aluminum. The manufacture was carrie...

Data regarding bulk polycrystalline nickel samples obtained by powder metallurgy using Spark Plasma Sintering (SPS) are presented, with a special emphasis on the influence of a cold isostatic pre-compaction on the resulting morphologies and subsequent mechanical properties. Three types of initial powders are used, nanometric powders, micrometric powders and a mixture of the formers. For each ty...

Three-dimensional graphene networks (3DGN) have the potential to be used as a reinforcement for aluminum matrix composites due their unique wrinkled structure and cost-effectiveness. In this work, mechanical properties corrosion resistance of 3DGN in Al were systematically investigated. 3DGN/Al with weight ratios 0, 0.075, 0.150, 0.225, 0.300 prepared by powder metallurgy following ball mill sp...
