Investigation and Analysis of Metallurgical and Mechanical Properties of AA1100 using FSW

P. Vijayasarathi


The effect of processing parameters on the mechanical and metallurgical properties of two similar joints of AA1100 produced by friction stir welding was analysed in this investigated. Different FSW samples were produced by varying the rotating spindle speed of the tool as 800 and 1400rpm and by varying the alloy positioned on the advancing side of the tool. In all the experiments the horizontal feed rate is fixed at 75m/min. All the welds were produced perpendicularly to the rolling direction for both the alloys. Micro hardness (HV) and tensile tests performed at room temperature were used to evaluate the mechanical properties of the joints. In order to analyse the micro structural evolution of the material, the weld’s cross-sections were observed optically and SEM observations were made of the fracture surfaces.

Keywords:FSW; Aluminium alloys AA110; Mechanical and metallurgical characterization.
