Mechanical Properties Evaluation of a Spray Formed AA-6082 Aluminum Alloy

Abstract:

The spray forming technology combines in a single step the advantages of the rapid solidification techniques and high the productivity of the conventional casting processes, allowing obtention of preforms with a refined microstructure, almost without porosity and macrosegregation free. The development and research efforts are leading to interesting alloys and materials production. The rapid solidification processes inherent to the spray forming allow the production of alloys with different compositions from those obtained by conventional ingot processes. The aim of this work was to carry out mechanical properties characterization of a spray formed AA-6082 alloy. The hardness results are presented in different sections related to the height of the spray formed preform (in a three-dimensional arrangement). The material was evaluated in the as sprayed formed condition and after heat treatments of solution at 525 °C for 1 h and aging for 1 h, 10 h, 100 h and 500 h periods at 125 °C. It is showed that the spray formed AA 6082 aluminum alloy is very stable regarding hardness variation during aging.
