Mechanical properties of cold-worked 5083 aluminum
Technical Report
·
OSTI ID:5845145
Tensile and fracture-toughness tests of 25%-cold-worked 5083 aluminum and weld material were conducted. The tests showed that the aluminum is highly nonhomogeneous; its fracture toughness, elongation, and percent reduction in area varied greatly from point to point. This characteristic could significantly affect the design of 5083 applications. The weld material exhibited more uniform mechanical properties throughout the weld. However, its fracture toughness varied from 19 to 49 ksi.in./sup 1/2/. The weld-joint geometry affects the fracture characteristics of the joint.
