Faz-se, inicialmente, uma revisão das teorias relativas ao endurecimento e dos mecanismos de deformação plástica de ligas de duas fases com precipitados grosseiros. Em particular, apresentam-se os resultados relativos às observações metalográficas de estruturas perlíticas deformadas em ensaio de tração e por trefilação. Desenvolve-se, na parte experimental, o estudo da deformação plástica de estruturas perlíticas de aço carbono eutetóide, através de ensaios de tração e observação metalográfica das estruturas de deformação em: perlita parcialmente esferoidizada, perlita grossa e perlita fina. Fez-se a caracterização dos modos de deformação de estruturas perlíticas para pequenas deformações. Obtiveram-se evidências de operação de sistemas de ...
