Creep Characterization of Aluminium Alloy 6061 at Elevated Temperature With Iron Oxide as Reinforcement

Abstract

To improve the engineering usage of the metal matrix composites, numerous challenges newlinemust be overcome. Exploration endeavors needed to defeat these challenges span the newlinespectrum from essential, basics situated examination, to more applied engineering newlineprojects. A great deal of work till date has concentrated on aluminum matrix composites, newlineyet iron oxide reinforcement composites do offer guarantee in definite applications. These newlineinclude aerospace, automobile, marine and industrial applications. Hence they merit newlineinvestigation, again with accentuation on essentials, instead of the advancement of newlinespecific composite. newlineThe main objective of this research work is to investigate the mechanical properties of the newlinealuminum matrix iron oxide reinforced composites. The Aluminum 6061 alloy is used as newlinea matrix and 2wt. %, 4wt. % and 6wt. % of iron oxide (Fe2O3) particles of size 40µm is newlineone used as reinforcement, the composite is prepared using the stir casting method. SEM newlineanalysis has been carried out to identify the matrix-reinforcement distribution in the said newlinecomposite. EDX analysis has been conducted to identify presence of the main constituent newlineelements in the aluminum-iron oxide particulate composites. newlineThe specimens prepared from the castings are tested as per the ASTM standards for the newlinemechanical properties like hardness, impact, tensile, bending, vibration and creep newlinebehaviour of the aluminum-iron oxide composite. From the results of the experimentation newlineit is seen that the increasing percentage of reinforcement, up to 4wt. %, increases the newlinemechanical properties of the aluminum-iron oxide composite. newlineThe bonding between the matrix and reinforcement of aluminum-iron oxide composites is newlinethe significant reaction between them, due to which the homogeneous distribution and newlinefine, well bonded microstructure, is obtained in the aluminum-iron oxide particulate newlinecomposites, thus enhanced mechanical properties have been observed. At 4 wt.% of newlineFe2O3, the maximum enhancement has been observed. newlineFrom the experimental
