چکیده انگلیسی
Friction stir lap welding-a precursor to the friction stir cladding- stainless steel on plain carbon steel was attempted. Refined microstructure with fully recrystallized austenitic grains with â¼3â¯Î¼m grain size and intermixing with base steel sample resulted in defect free lap weld. The pin affected region of the base carbon steel resulted in grain refinement from initial grain size of 8â¯Î¼m to 2â¯Î¼m. The microhardness values across the joint line showed stable values of â¼250â¯HV on the stainless steel side and â¼200â¯HV on the carbon steel side. Lap shear tests showed consistent load bearing capacity of â¼7â¯kN for the stainless steel-carbon steel joint. The weld between stainless steel and carbon steel showed 100% joint efficiency with similar yield strength of â¼440â¯MPa as the base steel sample and with an increase in ultimate tensile strength to â¼600â¯MPa as compared to â¼500â¯MPa for the base steel sample. The failure of clad tensile samples occurred in the base steel plate. Corrosion characterization of the clad surface was conducted in 3.5â¯wt.% sodium chloride solution. The potentiodynamic polarization showed positive corrosion potentials with a large passive range of â¼500â¯mV for the clad surface and a decrease in corrosion rates by more than an order as compared to the base steel sample. The friction stir lap welded stainless showed similar electrochemical properties as of the base stainless steel sheet.
