Torsional deformation and fatigue behaviour of 6061 aluminium alloy

Torsional deformation and fatigue behaviour of both solid and thin-walled tubular specimens made from as-received and heat treated 6061 aluminium alloy were studied. 6061 aluminium alloy have been widely used as a candidate material in automobile, aerospace, aircraft and structural application becau...
