“…The study on the effect of rotational speeds on friction stir welded Ti4Al2V alloy revealed that the increment in rotational speed was directly proportional with the welded hardness. 19 This shows that, for every alloy there is a suitable rotational speed which can create a sufficient frictional heat for a specific material to reach at its plasticization temperature or temperature at which the sufficient bond between particles are created. Investigation on the mechanical property of AZ61 at different rotational speed and welding speed ratios resulted in joint efficiency of 102.4% at a rotational speed of 400 mm/min, this is an indication that the AZ61 could well plasticized by using a rotational speed of 1200 rpm in 400 mm/ min.…”

Nowadays metal matrix composite materials are preferable in automotive and aerospace industries due to their mechanical properties and essentially attractive strength to weight ratios. However, their availability in use is limited because of their manufacturing method difficulty and process extravagancy. The aim of this research was to fabricate metal matrix hybrid composite through a novel approach thermo-mechanical method called friction stir consolidation (FSC) process. XRD result witnessed the presence of SiC, ZrO2, and AZ61 alloy phases. Different compositions of AZ61, SiC, and ZrO2 powder were taken into consideration and the progression of the FSC process were examined through properties of compressive strength, hardness, density, and porosity. For instance, the compressive yield strength of composition 85%Vol. of AZ61, 10%Vol. of ZrO2, and 5%Vol. of SiC accounts 164.2 MPa with an acceptable 2.2451 g/cm3 and 0.593% density and porosity respectively. However, when the strength to weight ratio was taken into consideration, 95%Vol. of AZ61, 2.5%Vol. of ZrO2, and 2.5%Vol. of SiC composition attained highest strength to weight ratio value. Additionally, the compressive yield strength value increased directly proportional with the ZrO2 volumetric composition. Likewise, the fractured surface of sample acquired highest strength to weight ratio was examined through SEM Fractography analysis.
