For the objective of this investigation, a comparison will be made between the hardness of cast aluminium alloy AA5083 and that of a metal matrix composite that contains silicon carbide at a weight percentage of 4%. Methodologies and Instruments for Research: Through the use of the stir casting technique, two distinct compilations of composites were produced. A total of twenty specimens were employed by the control group, which utilised the as-cast aluminium alloy AA5083. On the other hand, the experimental group utilised aluminium alloy that was enhanced with four percent silicon carbide composite. Throughout the entirety of the tensile strength testing, the ASTM-D2583 standard was adhered to. When adopting this method, twenty individuals from each group are chosen with a G-Power percentage of eighty percent. However, the metal matrix composite consisting of AA5083 and 4 percent SiC has a mean hardness value of 72.26 BHN, which is significantly higher than the mean surface hardness value of 57.06 BHN that AA5083 possesses when it is cast. From the results of the independent sample t-test, it can be concluded that the level of significance is p = 0.001 (p < 0.05). The findings of this study indicate that the tensile strength of the innovative composite samples, which were constructed from an aluminium metal matrix and contained four percent silicon carbide microparticles, increased by twenty-seven percent in comparison to the control samples. This was accomplished within the parameters of this research. [ABSTRACT FROM AUTHOR] |
