Good Castability considered the most important heat treatment Aluminum Alloy Al-5083 process as it helps to stabilize the microstructure. This alloy comes in the category of Non-Ferrous Materials wrought aluminum alloys. Normally, Aluminum This increase in demand for these alloys alloy 5083 has 2.5% magnesium which is the is because of their unique characteristics like major alloying element and 0.25% chromium. corrosion resistance, lightweight, nonmagnetic The designation to this type of alloy is and a good conductor of heat and energy. Apart comprised in the following manner, the first from these advantages over the ferrous materials, digit indicates the major alloying element which these significant losses strength with increase in is magnesium here, and next digit describes the temperature and also these have a tendency for type of modification and the third and fourth hot shortness and as compared to ferrous place for other alloying elements. This alloy is materials they shrink more. They are basically basically popular due it properties like good used for the following reasons: workability, good mechanical strength, and very 1.

As it belongs to the group of 53 HV0.3 but elongation is only 1.75 %. After aluminum alloys it bears the same properties as cold-rolling and the annealing treatment, the that of other aluminum alloys like low density SEM micrographs and the DRX patterns show and good thermal conductivity. This alloy is not more secondary phase precipitates and more heat treatable which means it can’t be hardened intermetallic formed. With an increase of by heat treatment, so it is hardened by cold annealing temperature, the amount of work. precipitates increases and work hardening Mechanical Properties of Material decrease, continuously. The elongation is Characteristics of any material which improved to 36 % but the tensile strength is describes the materials behavior under external decreased to 86 MPa after the annealing at 350 loads are commonly referred as mechanical °C for 1 hour. properties. As we know that all engineering Singh et al.

It was shown that both tool mechanical properties greatly rely on the types produce high-quality butt joints free from structure of the material, especially about the defects or imperfections as the visual inspection microstructure arrangement. Commonly known was done. The best tensile performance was mechanical properties are Strength, Hardness, obtained for FSW joints produced by a taper tool Toughness, Resilience, Stiffness, Elasticity, and the results obtained for joints produced by Plasticity, Ductility, Malleability, etc. threaded tool shoulder are significantly lower. LITERATURE REVIEW Tensile strength test indicated that welding Studies on the mechanical properties of speed is the main parameter which affects the Aluminum alloy Al 5083 have been made by tensile strength. Feed rate and tool shape are various scholars in the past. The majority of effecting second and third respectively. As the these studies were focused on the mechanical Impact toughness and Micro-hardness test are properties of Aluminum alloy Al 5083 but very conducted, the Feed rate is the main factor, less studied its mechanical properties in the Welding speed, Tool shape are effecting annealed condition. respectively.

For this properties. The differences between mechanical reason, microstructures, microhardness, and properties using different parameters were tensile tests were studied. From the most predicted based on a recently elaborated important results, the optical micrographs show mathematical model developed for FSW joints. that with increasing cold-rolling reduction rate, Bhowmiket. al.

Shrivas& Kale [4] during his research During the investigation, the pit morphology on aluminum alloys increases drastically in the polarized aluminum alloys showed automobile and aerospace industries. The hemispherical isolated deeper pits on the 5083 aluminum alloy takes the advantage of „strength alloy. Samples of the 1100 alloy revealed a to weight ratio ‟ and corrosion properties over higher number of shallow pits (more close to another structural element such as steel and its patches of general dissolution). The results alloys. The altered mechanical properties are showed that the type of intermetallic particles in achieved in aluminum alloy by using different the aluminum alloy played a major role in strengthening techniques such as age hardening passivity breakdown and pit morphology in etc. The favorable mechanical properties are seawater. It was reported that the corrosion explained by revealing the microstructure of resistance of 1100 alloy is better than 5083 in corresponding alloy and intermediate phase seawater both at room temperature and at 60 ºC. compounds during formation of the Also, it was found that with increasing the corresponding alloy. Hence the study of temperature the corrosion intensity also microstructure and their impact on mechanical increases. In addition, low corrosion rate values properties is essential.
