MATERIAL PROPERTIES OF ALUMINIUM REPORT FROM LABORATORY DEMONSTRATIONS ON 4 APRIL 2019 CIVL2110 MATERIALSXINHUI PENG 480398389 26/05/2019 ABSTRACT This report describes several tensile deformation tests using five aluminium alloy coupons base on the standard AS 1319 - 2007. The main aim of the tests was to obtain the stress strain curves for different types of aluminium alloy coupons as well as obtaining the composition and/or microstructure of each aluminium alloy and how it influences the presence of their different mechanical properties. Detailed test methods are described. It was found that five aluminium alloys exhibited a linear behaviour then turned to elastic behaviour. Pure aluminium had a yield stress of 11.67MPa, an ultimate strength of 56.062MPa, an elastic modulus of 2326.8MPa, and a strain at failure of 45%. Al 6006-solution heat treated had a yield stress of 16.58MPa, an ultimate strength of 70.759MPa, an elastic modulus of 5540.2MPa, and a strain at failure of 32%. Al 6006-ageing treatment 1 had a yield stress of 15.98MPa, an ultimate strength of 75.927MPa, an elastic modulus of 5534.6MPa, and a strain at failure of 34%. Al 6006-ageing treatment 2 had a yield stress of 10.53MPa, an ultimate strength of 75.819MPa, an elastic modulus of 4175.6MPa, and a strain at failure of 33%. Al 6006-ageing treatment 3 had a yield stress of 110.40MPa, an ultimate strength of 77.356MPa, an elastic modulus of 3712.8MPa, and a strain at failure of 33%. As a conclusion of the comparison of five aluminium alloy coupons, aluminium alloy would have the best behaviour after solution heat treatment without the presence of ageing treatment (eg. Since with the highest elastic modulus and the yield strength) which further solves the poor behaviour of pure aluminium at high standard of stress.

Material Properties of Aluminium (CIVL2110 Materials 2019)1 INTRODUCTION The aim of this report is to describe tests to investigate the material properties of aluminium in tension and concrete in compression, and in particular, present the stress-strain curves. By obtaining the stress strain curves for different types of aluminium alloy coupons as well as obtaining the composition and/or microstructure of each aluminium alloy and how it influences the presence of their different mechanical properties.
