“…It is observed that iron zirconium oxide depends on the sintering temperature and time. 11 Gupta et al studied fabrication of iron (Fe)aluminium oxide (Al 2 O 3 ) metal matrix composite by powder metallurgy technique at different sintering temperature and corrosion behaviour of the composite material by electrochemical method. 12 Garg et al studied the effect of sintering temperature on the structural and mechanical behaviour of Al-Graphene composite.…”

The present paper reports the effect of aluminium oxide and titanium oxide reinforcement on the properties of aluminium matrix. Aluminium matrix reinforced with aluminium oxide–titanium oxide (2.5, 5.0, 7.5 and 10 wt.%) in equal proportion were prepared by stir casting. Phase, microstructure, energy dispersive spectroscopy, density, hardness, impact strength and tensile strength of prepared samples have been investigated. X-ray diffraction reports the intermediate phase formation between the matrix and reinforcement phases due to interfacial bonding between them. Scanning electron microscopy shows that aluminium matrix has uniform distribution of reinforcement particle i.e. aluminium oxide and titanium oxide. Density of composite decreases due to variation of reinforcement and it shows low density after preheating. Hardness decreases due to the amalgamation of reinforcements. Impact strength was found to increase with the addition of reinforcements. Hybrid composite of aluminium matrix and (5% aluminium oxide + 5% titanium oxide) reinforcements have maximum engineering and true ultimate tensile strength. It is expected that the present hybrid metal matrix composites will be useful for aircraft rivets.

The aim of the present study is to investigate the effect of alumina (Al2O3)–carbon (C) reinforcement on the properties of aluminium matrix. Aluminium matrix reinforced with Al2O3–carbon (2.5, 5, 7.5 and 10 wt.%) in equal proportion was prepared by stir casting. Phase, microstructure, EDS, density, hardness, impact strength and tensile strength of prepared samples have been investigated. X-ray diffraction reports the intermediate phase formation between the matrix and reinforcement phase due to interfacial bonding between them. Scanning electron microscopy shows that Al matrix has uniform distribution of reinforcement particles, i.e. Al2O3 and carbon. Density decreases due to variation of reinforcement because ceramic reinforcement has low density. Hardness decreases due to variation of carbon since it has soft nature. Impact strength was found to increase with addition of reinforcement. Hybrid composite of Al and 5% Al2O3 + 5% carbon reinforcement has maximum engineering and true ultimate tensile strength. It is expected that the present hybrid metal matrix composites will be useful for fabricating stock screws.

“…In this direction, researchers have reported the mechanical and wear properties of various ceramic-reinforced Fe-based metal matrix composites processed using P/M. 7–10 Gupta et al 11 observed that wear rate of Fe-Al 2 O 3 metal matrix composites was dependent on the sintering temperature and time. Adhesive wear was found to be dominant at lower load, while abrasive wear was instrumental at higher load.…”

The present work investigated the wear behaviour of powder metallurgy-processed ZrO2 (10 wt.%) reinforced Fe-based metal matrix composite under dry sliding conditions. The friction and wear properties were evaluated under varying loads and sliding speeds ranging from 5 to 10 N, and 0.75 to 1.25 m/s, respectively. The wear tests were performed against a counter face of EN31 steel (HRC 60) employing pin-on-disc tribometer under room temperature. Microstructural examination of the composite by field-emission scanning electron microscopy (FE-SEM), equipped with energy dispersive spectroscopy (EDS), displayed the presence as well as a homogeneous dispersion of reinforcement phase into the matrix. At a particular load and sliding speed, transition behaviour was observed in the coefficient of friction, whereas wear rate increased with increasing load and sliding speed. The analysis of worn surface indicated that the adhesive wear was dominant at relatively high operating conditions, while abrasive wear remained operative at lower load and sliding speed.
