Aluminum based metal matrix composites (MMCs) have received considerable attention in the automotive, aerospace and nuclear industries. One of the main challenges using Al-based MMCs is the influence of the reinforcement particles on the corrosion resistance. In the present study, the corrosion behavior of Al-B₄C MMCs in a 3.5 wt.% NaCl solution were investigated using potentiodynamic polarizat...

Abstract Aluminium metal matrix composites (AMCs) have become quite popular for light weight, low cost, and good workability. The present work reports the impact of silicon carbide (SiC) reinforcement on physical, microstructural, mechanical characteristics Al-4032/SiC with 4, 6, 8% SiC (particle size 54?m) fabricated through bottom pouring stir casting set-up. Density porosity measurements AMC...

Background: Improvement of the mechanical and tribological properties due to extrusion can be attributed to the improved density and excellent bond strength due to high compressive stress. Methods: To avoid the product defects mathematically contoured cosine profiled die was used for the thermomechanical treatment. Improvement of mechanical characterization like density, hardness, compression t...

Hybrid metal matrix composites are new invention in material science and Engineering. The hybrid (Hybrid MMC’s) generally consist of two or more reinforcements it. These MMC’s have several benefits over the single reinforcement. presence it exhibits improved mechanical, tribological machinability properties. Aluminium-based made attention recent years as engineering materials. But some use rein...

Ilmenite is a valuable industrial mineral containing Fe and Ti elements. Two composites with different morphology and composition were produced using the reaction of synthesized ilmenite and aluminum. The molar ratios of 1:2 and 1:8 were selected. The critical temperatures of each molar ratio were determined using the Differential Thermal Analysis (DTA). The heat treatment of the systems ...

In this study, the elemental powders of aluminum and copper were initially subjected to mechanical alloying using an attrition ball mill under argon atmosphere to produce an Al-4.5 wt% Cu powder alloy. The WC nanoparticles were then added to the powder alloy and milled in a planetary ball mill to explore the role of the WC nanoparticles on the mechanical properties of the fabricated composite p...
