Abstract
AA2014 is most widely used metal among the aluminium alloy series due to its exceptional corrosion resistance, low density rate, and it can maintain high strength and toughness at various temperatures. So, these materials have their application in the aerospace, military and the automotive sector. The present work focuses on evaluating the mechanical properties such as ultimate Tensile strength (UTS), Yield strength (YS), and percentage of elongation using Uniaxial Tensile test. The three controllable factors used in the present study are temperature ranging from 200 to 300°C with 50°C increment, orientation 0,45,90 degree relative to the rolling direction and strain rate 0.001,0.01 and 0.1mm/sec. A total of 27 experiments were planned and conducted based on the design of experiments. Experimental results show that with increase in strain rate increasing of material properties furthermore with increase in temperature decrease of material properties and increase in the percentage of elongation was observed. In addition to that ANOVA analysis was carried out and noticed that strain rate is most effecting parameter for UTS and temperature is most effecting parameter for YS and percentage elongation. The fracture specimens from uniaxial test are investigated for type of fracture through microstructural studies
