Effect Of Overaging On Tensile Properties Of 2219-T852 Aluminum, Austin Bitter, Tristan Koyamatsu
Effect Of Overaging On Tensile Properties Of 2219-T852 Aluminum, Austin Bitter, Tristan Koyamatsu
Materials Engineering
This project investigated the overaging performance of aluminum alloy 2219-T852 for use in high temperature applications. 2219 aluminum is an alloy containing 5.8 to 6.8 percent copper, and is classified as a high strength age hardenable alloy. The sponsor for this project, Weber Metals, hopes to use 2219 Al to replace titanium in certain applications above the thermal limits of typical high strength Al. To test its performance, they manufactured round tensile samples and delivered them in peak aged, T852 condition. These samples were then overaged at a range of times and temperatures. The times in this experiment were one …

Rotating Beam Fatigue Of Forged 2219-T852 Aluminum Alloy, Julio Escamilla, Madison Reed
Materials Engineering
2219 aluminum has been used extensively in aerospace applications due to its ability to retain strength in large section thicknesses, thus making it ideal for large forgings. However, the Metallic Materials Properties Development and Standardization (MMPDS) handbook, a source of design data for aerospace industry applications, lacks information on 2219 in the T852 condition, particularly concerning the behavior of the alloy under cyclic loading conditions. Data was collected for forgings of 2219-T852 aluminum as produced by Weber Metals to determine the fatigue life of the alloy-temper combination and to assess the effects of forge thickness and orientation on fatigue life. …
