Mechanical and Tribological Behaviour of Aluminium Metal Matrix Composites Using Powder Metallurgy Technique— a Review
Aluminium metal matrix composites are widely used in engineering applications, specially automobile, aerospace, marine and mineral processing industries owing to their improved wear properties compared to conventional monolithic aluminium alloys. Presently hybrid composites plays vital role in engineering application. The researchers who developed composites, were subjected to many characterisa...
متن کاملSynthesis and characterisation of hot extruded aluminium-based MMC developed by powder metallurgy route
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...
متن کاملMetallurgy of the U
This report describes the composition and some properties of the cast iron and wrought iron that form the dome of the U.S. Capitol. It is a compilation of two recent investigations, one by NIST and one by Lucius Pitkin, Inc. These investigations were implemented by the Office of the Architect of the Capitol to determine the dome’s condition and also to predict how the outer shell might respond ...
متن کاملA hazardous waste from secondary aluminium metallurgy as a new raw material for calcium aluminate glasses.
A solid waste coming from the secondary aluminium industry was successfully vitrified in the ternary CaO-Al(2)O(3)-SiO(2) system at 1500 degrees C. This waste is a complex material which is considered hazardous because of its behaviour in the presence of water or moisture. In these conditions, the dust can generate gases such as H(2), NH(3), CH(4), H(2)S, along with heat and potential aluminoth...
متن کاملElectro Discharge Machining Characteristics of Mg/SiCP Metal matrix composites by Powder Metallurgy (P/M) Techniques
The objective of this work is to investigate the effects of current, pulse on time and pulse off time in Electro Discharge Machining performance on material removal rate and tool wear rate of Mg/SiCp metal matrix composites. In this work the Mg/SiCp metal matrix composite specimens were prepared by powder metallurgy route. ELEKTRA PLUS spark erosion machine was used for the purpose. Brass tool ...
