Hot formability and microstructural development of spray-deposited Al-Li alloy and composite.
The deformational and microstructural behaviour of the commercial Al-Li alloy 8090 and an 8090 based composite containing silicon carbide particulate has been investigated. The materials were deformed at elevated temperature by the test methods of plane strain compression (PSC) and torsion to …

Effect of surface treatment on the mechanical properties of the polysulfone-Al/Li bonded system including thin film studies of moisture intrusion and the viscoelastic response of the interphase region
An investigation of polysulfone-Al/Li alloy interaction involved single lap shear joints and wedge samples following an FPL etch, sulfuric acid anodization (SAA) and phosphoric acid anodization (PAA). The study of the Al/Li surfaces involved the determination of the elemental composition and …

Exploration of incompatibility in Al-Li alloys using high energy diffraction microscopy and a crystal plasticity model
Aluminum-lithium (Al-Li) alloys have inherently desirable properties such as increased specific stiffness and strength. Without question, these alloys would be candidate materials for many aerospace structural designs if it were not for a complicated and confounding mode of fracture termed …

In situ measurement of lattice strain using synchrotron radiation and a conical slit system
An experiment utilizing synchrotron radiation to measure lattice strain components from an aluminum-lithium sample during tensile loading is presented in detail. The conical slit system at Argonne National Laboratory’s Advanced Photon Source is utilized to isolate a single grain with an orientation …
