Resumo

A Prensagem em Canais Equiangulares (ECAP) é de longe, a técnica mais promissora, pelo método de deformação plástica severa (SPD) sendo capaz de produzir grandes volumes de materiais suficientes para aplicações práticas. O processo ECAP pode ser repetido até que a saturação de refino seja atingida, levando a grandes quantidades de deformação cisalhante. A razão por trás das propriedades excepcionais obtidas em materiais processados por ECAP foi atribuída à microestrutura do material obtida nesse processo de deformação.  Este trabalho investigou na literatura as variáveis de deformação do ECAP afim de analisar o efeito de cada uma destas na microestrutura dos materiais processados. Os artigos foram colhidos das bases de dados: ScienceDirect e biblioteca eletrônica Scientific Electronic Library Online (SciELO), por contemplarem a literatura nacional e internacional. Baseando-se nos resultados encontrados, pôde-se perceber que diversos parâmetros devem ser analisados para deformar metais puros e ligas, para refinar a microestrutura, como ângulo de curvatura e ângulo de canal da matriz de deformação, número de passagens, e temperatura de prensagem. Foi possível verificar que alterações nessas variáveis configuram alterações na microestrutura.
