A Novel Investigation on Tensile Strength, Compressive strength, Hardness and Corrosion resistance of A16061 Composite with Weight Fractions of 5%, 10% and 15% SiC and Comparing the Outputs with as-cast A16061

Abstract

The aim of present investigation is to find tensile strength, compressive strength, hardness and corrosion resistance of A16061 metal matrix composite (MMC) with weight fractions of 5%, 10% and 15% Silicon Carbide (SiC) and compare the same with that of as-cast A16061. Al-SiC MMC plate of thickness 10 mm and dimension <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$150\mathrm{x}150$</tex> mm was used in this research work. Al-SiC MMC composite was made with different weight fractions (5%, 10% and 15%) of SiC using stir casting method. The SiC reinforcements were preheated to 6500C and stir casting was carried out at 8000C temperature. Tensile, compressive, hardness and corrosion resistance tests were carried out as per the ASTM standards. Test samples (N = 20) were taken from each plate of experimental group (5%, 10% and 15% weight of SiC/Al MMC) and control group (as-cast A16061). One way ANOVA using SPSS software revealed that Aluminium MMC with 15% weight of SiC has significantly higher tensile strength (354.882 MPa), compressive strength (299.563 MPa), hardness (102.5 HV) and corrosion resistance (1.840 mm/year) than that of Aluminium MMC (with 10% and 5% weight of SiC) and as-cast A16061 with significance level of 0.00 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(\mathrm{p}\unicode{x00A1}0.05)$</tex> .
