1. Caracterizações de propriedades microestruturais e mecânicas de ligas AA 1100 e AA 5052 processadas pela técnica de laminação acumulativa ("Accumulated Roll Bonding - ARB"). / Characterization of microestrutural and mechanical properties from AA1100 and AA5052 alloys that were processed by Accumulated Roll Bonding - ARB.
The present work is related to the production, in a laboratory scale, of a metallic microstructure having a grain size smaller than one micrometer, through the Accumulated Roll Bonding technique(ARB), for two different aluminum alloys, namely AA 1100 and AA 5052. The strips obtained by the ARB technique have been characterized by their mechanical properties

2. Avaliação da replicagem de moldes torneados com ferramenta de diamante usando prensagem a quente em polimetilmetacrilato (PMMA) / Evaluation of the replication of molds generated from single point diamond turning using hot embossing in polymethylmethacrylate (PMMA)
In this work, different types of microstructures were generated by single point diamond turning and microindentation for will replicated through the hot embossing. Tests were carried to evaluate the generation these microstructures by two distinct methods: micro-deformation and micro-machining, planned to observe the replication of the mark generated by the
