1. Mechanical Properties and Metallurgical Characterization of LM25/ZrO2 Composites Fabricated by Stir Casting Method
ABSTRACT Zirconia (ZrO2) dispersed aluminum alloy metal matrix composites produced by stir casting techniques. Using stir casting techniques, aluminium based composites with varying amounts of 3%, 6%, 9%, and 12% of zirconia by weight are fabricated. The prepared samples were subjected to physical, mechanical,tribiology and microstructure investigation. The

2. Study on Effect of EAFD Particulate Reinforcement in AA7075 Aluminum Matrix Composites
Eletric arc furnace dust is dangerous solid waste that is generated in steel manufacturing processes. The utilization of the dust from these industries avoids disposing it into industrial waste landfills and saves costs. In this study, an attempt has been made to fabricate aluminum matrix composites reinforced with EAFD particulate, throught the conventional

3. Evolución microestructural de una aleación de aluminio A356 con y sin reforzamiento. de SiC sometida a molienda mecánica
ABSTRACT The effect of milling time on the crystallite size, microstrain and Vickers microhardness, of an aluminum alloy A356 (Al-7wt % Si) with and without SiC reinforcement (15 wt%) was studied. The metal alloy powders were obtained by the rotating electrode process (REP) from cylinders of the alloy, the obtained powders present spherical morphology with a

4. Mechanical characterization of PM aluminum composites by small punch test
ABSTRACT In this work Small Punch Test (SPT) was applied to study the mechanical behavior of ultrafine-grained Al-Al2O3metal matrix composites (MMCs) fabricated in situ via powder metallurgy route (HITEMAL®). Such MMCs show attractive mechanical properties, enhanced creep performance and increased thermal stability at elevated temperatures, not normally ass

5. Using Severe Plastic Deformation to Fabricate Strong Metal Matrix Composites
The processing of bulk metals through the application of severe plastic deformation leads to significant grain refinement and a consequent strengthening of the material. High-pressure torsion (HPT) generally refers to the processing of disk samples and this technique is especially effective in producing extremely small grains. Recently, new experiments were

6. Weldability Study of LM25/ZrO2 Composites by Using Friction Welding
ABSTRACT In this paper aluminum (LM25) alloy was chosen as a base matrix metal, and it was reinforced with 0, 3, 6, 9, 12% of Zirconium dioxide (ZrO2) particulates based on weight fraction method. Stir casting method was used to cast LM25/ZrO2 composite material. The cast samples were subjected to physical and mechanical test viz, density, hardness, tensile,

8. Low Temperature Sintering of Aluminum-Zircon Metal Matrix Composite Prepared by Spark Plasma Sintering
Aluminum-15 wt. % zircon metal matrix composite was fabricated using spark plasma sintering method at the temperature of 450°C and holding time of 4 min. The bending strength of 284±21 MPa and microhardness of 171±14 Vickers were determined for produced composite. XRD investigations proved that almost no decomposition of zircon particles as reinforcement

9. Enhancement of Mechanical Properties of Aluminum and 2124 Aluminum Alloy by the Addition of Quasicrystalline Phases
A structural and mechanical characterization of pure aluminum and 2124 T6 aluminum alloy reinforced with quasicrystalline phases of composition Al65Cu20Fe15 and Al70.5Pd21Mn8.5 (%at.) were performed. The quasicrystalline phases were synthesized by arc melting and then milled to produce powder of the alloys, which were then mechanical mixed with the starting

10. Microwave Sintering of Aluminum-ZrB2 Composite: Focusing on Microstructure and Mechanical Properties
Abstract Microwave assisted rapid sintering was carried out to fabricate aluminum-ZrB2 metal matrix composites containing 1 wt% cobalt and 10, 15 and 20 wt% ZrB2 as the reinforcements at temperatures of 600, 700 and 800°C. The results showed that the highest values of density and bending strength (97% of theoretical density and 240 MPa, respectively) were o
