Research on Synthesis of High-Strength Aluminum Alloys. Part II.
Abstract
The program is divided into two tasks. The objective of Task A is to optimize the properties of aluminum alloys by controlling the concentrations and sizes of the small, intermediate, and large precipitates. Systematic variations in chemistry and also in the homogenization and aging treatments have provided a range of concentrations and sizes of the various precipitates in a series of alloys based on the 7075 and 2024 alloy compositions. Procedures for fracture toughness measurements of thin sheet material have been developed. Fatigue tests have also been conducted. The objective of Task B is to develop a recrystallized microstructure in wrought high-strength aluminum alloys during hot working. The desired microstructure is being sought by control of hot-working conditions and also control of alloy composition. (Modified author abstract)
