Effect of Forging Condition on Mechanical Properties of Al/SiC Metal Matrix Composites

Abstract

The objective of the research work to investigate effect of forging condition on mechanical properties of Al/SiC composites prepared in open die at the temperature of 450 °C with three different stages then specimens are aged at T6 conditions. Forged specimens subjected tensile, compression and hardness tests to evaluate effect of forging levels on Al/SiC composites. The effect of plastic deformation and high temperature during forging led to a recrystallization of the Al/SiC matrix with a grain refinement. At first and second stage higher grain refine could be seen but at third stage no further grain refinement could be absorbed. The modification of grain which was influenced an enhancement in the mechanical strength. The scanning electron microscope shows the brittle and ductile mixture failure was absorbed in all type of the specimens. Forging improve the mechanical properties with nominal loss of ductility.

A review on primary synthesis and secondary treatment of aluminium matrix composites

“…The aforementioned improvement properties were adduced to even dispersion of fly ash particles and grain structure refinement as percentage rolling reduction increases. In Hanamantraygouda and Shivakumar (2015), Al-SiC based composites subjected to hot forging at a temperature of 450 C and aged at T6 conditions were examined. It was shown that the treated Al-SiC based composites exhibited improved tensile strength, compressive strength and hardness properties although with insignificant detrimental effect on ductility.…”

“…In addition, there is only a small fraction of fracture surface that is dominated by small dimples. These small dimples are generally distributed at the boundaries between the fits, probably due to the ductile rupture of the magnesium matrix This has large number of dimple shaped structures no crack found (20). The presence of dimples displays the typical ductile fracture of the matrix alloy.…”

Synthesis and Mechanical Property Evaluation of Hot Forged Aluminium Alloy Reinforced with Nano Alumina

“…MMNCs can be formed by conventional deformation processes such as rolling, extrusion or forging, among which forging has been used as the secondary processing for its excellent preferential axial alignment of discontinuous fibers as well as compressive hydrostatic state of stress [7][8]. The forged nanocomposites exhibit reduced porosity, a more uniform particle distribution and improved ductility [9][10].…”
