Al and Mg Alloys for Aerospace Applications Using Rapid Solidification and Powder Metallurgy Processing.
Abstract
This report covers the progress made in the first year of a three year study on the rapid solidification processing (RSP) of Al-and Mg based alloys. In this study, effort has been applied in three areas: (1) Processing (both particulate production and consolidation), 2) Microstructural effects, and (3) Mechanical Properties. The underlying objective has been to control the microstructure to obtain favorable mechanical properties. This will, perforce, entail a detailed understanding of the microstructures, as affected by factors such as alloy chemistry and processing variables, and, in turn, their effects on the mechanical properties. The microstructural changes which occur in heat-treated, as-rapidly solidified materials, as well as those in materials consolidated, either by extrusion or by the relatively new technique of dynamic compaction, have been investigated. The alloy systems studied include: (1) high modules A1 alloys, namely, Al-Mn and Al-Be, (2) Al alloys for elevated temperature applications, namely, Al-8Fe-2Mo, and (3) Mg alloys for elevated temperature applications, namely, Mg-20Gd and Mg-Li-Si. The report is divided into three major sections: (1) Brief overview of RSP of individual alloys, (2) Results, and (3) Future work. Individual sections are further subdivided as appropriate.
