Parallel Session 15: Advanced Materials 3

The development of reliable advanced micro-electronic interconnects that are free of toxic materials such as lead depends on an in-depth understanding of the microstructures that exist in individual solder joints. This research combines the synchrotron techniques of in-situ imaging and powder diffraction (PD) to give an understanding of the development and stability of these microstructures....
Light metal alloy components fabricated via powder metallurgy processes have significantly lower manufacturing costs compared to those formed by traditional methods. Traditionally, powders are made from bulk alloy ingots, but a number of recent reduction techniques allow high purity alloy powders to be generated directly from metal oxides.
The Powder Diffraction beamline at the Australian...
Precipitates influence the relative hardening of slip and twin in magnesium alloys. The current work employs in-situ synchrotron X-ray diffraction to investigate the role of precipitate shape (e.g. plates and spherical precipitates) on the strengthening of Mg alloys. The critical resolved shear stresses (CRSS’s) of dislocation slip and deformation twinning and the subsequent changes following...
Synchrotron radiation with high flux and high resolution gives us information that would not be possible from laboratory X-ray instruments. Synchrotron X-rays are available as an extremely intense beam that allow fast scattering or diffraction studies of energy storage materials. At synchrotron sources various techniques at different beamlines offer structural and chemical information on...
When a highly energetic heavy ion passes through a target material, the damaged region left in its wake often exhibits preferential chemical etching over the undamaged material. This etch-anisotropy can be used to create very high aspect ratio channels (pores) of up to tens of microns in length, with pore diameters as small as several nanometres. Membranes formed by this method are ideal for...
