Residual strength of aluminium alloy Afnor 7020
Source abstract
Abstract
Surface crack tension specimens of Afnor 7020 aluminium alloy (parent metal and weldment) were used to evaluate the residual strength in panels 5 mm thick and 125 mm wide. The reduction in the ultimate tensile strength (UTS) was in the range 9–15% in the parent metal for cracks up to about 4 mm deep. For similar crack depths in weldments the reduction in UTS was in the range 14–30%. The results have a significant bearing on the quality and reliability of welded components that are to be subjected to non-destructive evaluation.
