High-cycle fatigue behavior of friction stir butt welded 6061 aluminium alloy
DAS Hrishikesh, D Chakraborty, TK Pal - Transactions of Nonferrous …, 2014 - Elsevier
Friction stir welding (FSW) of 6061 aluminium alloy butt joint was carried out at each rotation
speed of 600, 800, 1000, 1200 r/min for two different travel speeds, 80 and 100 mm/min, at a
constant probe depth of 1.85 mm. The calculated energy input based on the FSW
parameters studied shows that the ultimate tensile strength (UTS) of the butt joint is obtained
within a certain range of energy input of 297 kJ to 354 kJ out of total range of energy input
studied from 196 kJ to 405 kJ. The fatigue behaviors of high-strength and low-strength joints …
