Processing and Properties of Advanced Aluminum Alloys

Abstract

This project has as its focus microstructure control for improving fracture resistance of advanced aluminum alloys. Our progress report is divided into two major parts: Part I which is concerned with the quench sensitivity of the Al-Li-Cu-Mg alloy 2090 and the effect of quench rate on fracture behavior, and Part II which is concerned with the recovery and recrystallization mechanisms that occur in an alloy having a high density of dispersoid particles. The grain size of aluminum alloys can affect both strength and deformation behavior and often controls the degree of superplasticity during elevated temperature deformation.
