Compilation of Mechanical Property Data for Improperly Quenched (Soft) Aluminum Plates
Abstract
Data is summarized from a number of investigations that dealt with the overall issue of substrength aluminum plates. An improper heat-treatment resulted in localized areas of the plates with low mechanical properties. For these plates it is shown that: tensile, compression, and bearing strengths are significantly reduced; fatigue properties are reduced, particularly for 2000- series alloys; fatigue crack growth rates are faster in 2000-series alloys but may be slower in high strength 7000-series alloys; stress corrosion properties are not reduced; toughness may increase; and the loss of strength can be reflected in electrical conductivity and hardness readings. This report also contains a statistical evaluation of tensile data from this study and other sources relating yield and ultimate tensile with electrical conductivity and hardness.
