Influência da temperatura de vazamento na tixoconformação de ligas A332 modificadas por estrôncio

Abstract

The development of worldwide industry, managers are looking for improvements in the production processes, as well as, the reduction of production time and better quality with low costs. The mechanical manufacturing processes have been evolving exponentially and thixoforming is contained in this evolution. The thixoforming consists in laying the material in semi-solid state, and after that, performing the mechanical conformation. The process makes it possible to produce parts on a large scale, with complex geometries and excelent surface quality. In it, it is not possible use many materials, so, one of most used materials is aluminum. In this final paper, the aluminum alloy, A332, with two casting temperatures was studied, which was added elements like boron, titanium and strontium, besides monitoring the changes that occur in the microstructure and mechanical resistance of the material after being thixoformed.
