Mechanical and physical properties of aluminium vs steel / Amni Wafiqah Mohd Arhafudin

Material properties consist of physical, chemical or mechanical that would determine the functionability of the material. The mechanical properties of a material reflect the relationship between its response to or deformation from an applied load or force. Types of mechanical properties are strength, hardness, ductility and stiffness.These properties are ascertained by performing carefully designed laboratory experiments that replicate as closely as possible the service conditions. The physical features that a material exhibits when forces are applied to it are known as mechanical properties. Currently, some researcher or manufacturer not able to choose the best materials for certain application, thus can make the materials fails and effect the fabrication cost and materials waste. If the researcher or manufacture choose the best material it will helps them to fabricate aircraft component and light weight industrial appliance with the optimum performance. The objective of this study is to investigate and compare the mechanical properties of aluminium and steel and relate with the theoretical analysis. Furthermore, to investigate the microstructural analysis of aluminium and steel at different magnification. Next, modulus of rigidity, maximum shearing stress, maximum shearing strain, and Poisson’s ratio will be measured by the tensile test. The mechanical properties of Aluminium and steel are examined by doing tensile test as the last way of investigation. It measures the force required to elongate a specimen to breaking point. As for the results, the samples will be characterized and evaluated as well as compared with aluminium and steel theoretical analysis. In conclusion, this project will help manufactures choose the best material for lightweight properties with good mechanical properties especially for aircraft components and industrial appliance.
