摘要：
The purpose of this study is to find the influence of volumetric percentage of High Entropy Alloys (HEA) on Mechanical Behaviour of 6061 T6 Al alloy surface composite processed by Friction Stir Processing (FSP). Al-6061-T6 alloy was considered as the base material and Al-Fe-Cu-Ni-Zn as HEA with relevant weight proportion. HEA were reinforced on plate by making a slot on them using shaper and varying the volumetric percentage of slot. Friction stir processing was carried out on the samples with optimal working parameters. Study of the properties such as microstructure of joint and strength will directly affect the parameters such as corrosion of joint which will decide the service and life of the joint in different environments. Radiography was carried out for the samples after FSP to check for any defects or cracks. The microstructures for all the samples are studied based on grain size refinement and uniform Distribution of HEA around the travel pattern of tool. It is observed that micro hardness of samples increased with increase in percentage of HEA which is more than the hardness value of base material (Al alloy). It is evident that 4% sample exhibits better tensile properties than other.
