Processing and Properties of Advanced Aluminum Alloys

Abstract

This research has been concerned with the use of processing to optimize the microstructure of advanced aluminum alloys for property improvement. The report was concerned with microstructure control and fracture. The focus was on the effect of shearable and non-shearable precipitates on slip behavior, void nucleation and fracture; the effect of composition on quench sensitivity and fracture; the effect of nonequilibrium eutectic melting during solution heat treatment on intergranular fracture; and the effect of slip behavior on fatigue crack propagation. Task II is covered in Part II of this report and was concerned with processing of advanced aluminum alloys for microstructure control for improvement of superplastic forming properties. The detailed studies of this task have allowed identification of the material and processing parameters that control development of the microstructural features required for superplasticity. Keywords: Particle size.
