Abstract

This study analyses the effects of process parameters on the mechanical properties of the developed unalloyed Aluminium sheet in Aluminium manufacturing industries. The process parameters investigated in this study were pressure and temperature, these process parameters poses great challenges on the mechanical properties of the produced unalloyed Aluminium sheets, this process parameter when not properly controlled results to catastrophic failure on the produced Aluminium sheet due to cracks developed during manufacturing. The mechanical properties studied in this research were tensile strength, hardness, Young Modulus of Elasticity and Shear modulus respectively. These properties were determined at various production temperatures and pressures which ranged from 660oC to 2400oC and 20GPa to 78GPa respectively. From the evaluation, an optimal tensile strength of 621MPa and 562MPa was obtained at a temperature of 1921oC and pressure of 72GPa respectively. The optimal young modulus of elasticity of 69GPa and 68GPa was obtained at a temperature of 1610oC and pressure of 69.5GPa respectively. The optimal shear modulus of 25.5GPa and 26.2GPa was obtained at a temperature of 1442oC and pressure of 69.5GPa respectively. The optimal Brinell Hardness Number of 61 was obtained at temperature of 1800oC and pressure of 69.5GPa respectively. The coefficient of determination R2 for the regression line equations for tensile strength, hardness, Young Modulus of Elasticity and Shear modulus ranged from 0.7254 to 0.9163, these results shows good adequacy of the experimental results obtained. The results obtained also shows that temperature and pressure have great effect on the mechanical properties of the developed Aluminium sheet produced in Aluminium manufacturing industries.
