Developing the Empirical Relationship to Predict the Minimum Microhardness of AISI 1020 Grade Low Carbon Steel Joints

Abstract:

In this research work, friction welding (FW) of AISI 1020 grade carbon steel rods of 12 mm diameter was investigated with an aim to develop the empirical relationship to predict the minimum micro hardness for the process parameters. Welds are made with various process parameter combinations using ANOVA design matrix which were subjected to Vickers hardness tests. A microstructure analyses was carried out to acquire the joint efficiency. The heat affected zone of the microstructure has been shown for the optimized condition.Keywords:-Friction welding, AISI 1020 grade carbon steel, empirical relationship, Grain structure, Micro hardness.
