Recent work on the solidification of hypereutectic Al-Si alloys (having between 15-20% silicon) has focused on the solubility of barium in the silicon phase.
Their results show that P added to the high-Si hypereutectic component provides prerefined primary Si particles.
The traditional defense by the minerals industry against erosion of slurry flow equipment has been to use specialized wear-resistant materials, such as white iron with various hypereutectic alloys and carbides.
The pistons are made with a hypereutectic alloy and designed with a thick crown area and use a special ring pack so that the boost pressure and heat generated by the turbo system can be handled.
The alloy is hypereutectic and based on nano-structural aluminum.
As number of alloying elements increases, the structure transits from hypo- to the hypereutectic one, the sign of which is presence of excessive carbides [8].
The block continued on page 150 and heads are of lightweight hypereutectic aluminum alloy.
Microstructures of Rapidly Solidified Hypereutectic Al-Si Alloy with Low-Titanium Content
Xiao, "Effect of heat treatment on microstructure and mechanical properties of a Ti-bearing hypereutectic high chromium white cast iron," Materials Science and Engineering: A, vol.
It is based on a concept that barium's solubility in the silicon phase demonstrates a hypereutectic aluminum silicon alloy can be produced without a primary silicon phase, thereby producing a microstructure exhibiting higher strength.
