Abstract

This work describes a proficient and innovative technique for billets production, by a modified direct thixo-injection transformation process of aluminun alloy Al356.1 chip briquettes. A thixo-injection device was built, coupled into a universal testing machine and an inductive heating system, monitored by a temperature acquisition device. The metallic solids of the globular structure, also known as refunded, are metallic alloys that have the final morphology of their microstructure changed to approximate as much as possible of a spherical geometric shape, completely escaping the traditional dendritic morphology of foundry, very common in non-alloys ferrous metals, especially in those with aluminum as the base metal. Depending on the fabrication technique employed, these refolded materials may additionally undergo a refining process, resulting in microstructures of nanometric magnitudes [1-5].
