The base Al-Zn superplastic alloy was investigated at 250°C to
determine the effect of small amounts of magnesium on mechanical
properties. Six alloys of nominal composition 0.00, 0.10, 0.25,
0.50, 0.75, and 1.00 weight percent magnesium, constant 78 weight
percent zinc, and variable 21 to 22 weight percent aluminum were...
The miniaturization of Microtechnology-based Energy, Chemical and Biological Systems (MECS) is made possible by the use of high aspect ratio microchannel arrays to increase the surface-area-to-volume ratio of the flow conduits within the devices, resulting in an improvement in the heat and mass transfer performance of the devices. However, advantages...
Aluminum single crystals were cyclically deformed in single-slip at small strain amplitudes
at 77 K to presaturation. The observed mechanical behavior is consistent with other
recent work. The dislocation substructure was analyzed in detail. The structure can be
described as consisting of dense bundles or veins of dislocation dipoles, separated...
