Aging kinetics of friction stir welded Al-Cu-Li-Mg-Ag and Al-Cu-Li-Mg alloys

Friction stir welding under ambient cooling conditions, using tool rotation rate of 800rpm and welding speed of 200mm per minute was carried out on 2195 and 2199 Al-Li alloys. Underwater welding was also performed on both the alloys using a pool on the top of workpiece. Post weld heat treatment for...
