All metallic materials are prepared from the liquid state as their parent phase. Solidification
is therefore one of the most important phase transformation in daily human life. Solidification …

This work describes the micro-and nanostructures of inert gas atomized Al-Cu alloy powder
particles over a range of compositions. For cold spray deposition, the microstructure and …

A vertical continuous compound casting technology for the production of rotationally
symmetric bilayer rods consisting of brass CuZn37 and aluminum AA7075 was developed …

Gas atomization is the most used powder production technique since it provides good
control on particles shape, surface oxidation and dimension. It is a rapid solidification …

An improved method is presented for determination of solidification curves, ie., fraction solid
vs temperature, for commercial Mg alloys using heat-transfer model (HTM) differential …

Impulse atomisation in helium and nitrogen and water atomisation have been utilised to
produce powders of D2 tool steel. It was determined that higher cooling rates result in a …

X-ray tomography using synchrotron radiation with 1-µm beam resolution at the European
Synchrotron Radiation Facility was used to generate three-dimensional (3-D) images for …

The rapid solidification of a peritectic alloy is studied. Various 2D and 3D characterization
techniques were effectively utilized to investigate the effect of cooling rate on both the phase …

A new technique is introduced to quantify microsegregation during rapid solidification. The
quantification involves calculation of the average solute solubility in the primary phase …

This work explores the use of Ce and rapid solidification to attain primary Si modification in a
hypereutectic Al-40wt-% Si alloy. Al–40Si and Al–40Si–1.5 Ce powders were produced by …
