Abstract Scope |
Experimental research was conducted to investigate the micro-hardness, corrosion resistance, and microstructure of an Induction Heated Friction Stir Welded AISI 410 Stainless steel. IH-FSW was carried out by using four varying parameters. Micro-hardness tests were conducted in the weld zone to assess the mechanical properties of the joints. The microstructure evaluation shows that the size of the grain at the nugget zone is fine in size while comparing with the parent metal. Due to dynamic recrystallization during the induction heated friction stir welding, well-equiaxed grains were found in the nugget zone. The 3 hours and 24 hours weight loss corrosion test methods were conducted by using 0.5 M H_2 SO_4, which shows that the corrosion resistance of the stir zone is better than the parent material. The given parameter combinations, tool rotation 1200 rpm, welding speed 45 mm/min, shoulder penetration 0.50 mm and induction heat input 450°C,exhibit the best results |
