25. Desenvolvimento de um processo para refino de grão do aluminio fundido baseado na aplicação de recobrimentos volateis ainterface metal/molde
This study describes the development of a/grain refining process for commercial purity Aluminium which is based in the introduction of a volatile addition (Hexacloroethane) to the mould coating. A critical review of the literature was made, which both indicated the originality of the present process and formed a theoretical base from which the concepts invol

26. Desenvolvimento de processos não convencionais de refino de grão na solidificação do aluminio e ligas aluminicas-cobre, sem adição de inoculantes ou agentes refinadores
The present work encompassed the development of grain refining processes as applied to commercial purity Aluminium and the Al-4,75 % Cu alloys, without addition of inoculants refining agents. The techniques used employed substrates high heat extracting potential) for copious nucleation of solid and the induction of flow in liquid metal wich encouraged detach
