Structure and Strength of a Permanent Connection between Stringer and Skin Formed by Direct Sequential Growth from Aluminum Alloy
摘要
Abstract
The structure and strength of permanent joints of stringer with aircraft skin obtained by direct layer-by-layer growth from aluminum alloys are studied in order to reveal the dependences of mechanical properties on the peculiarities of the formed alloy structure in the joints obtained. The microstructures and ultimate tensile tests of flat specimens were investigated.
