Description

The manifestation of superficial oxidation in creep rupture tests performed with three austenitic, stainless steels under constant load in furnaces open to the atmosphere, between the temperature of 5500C and 8000C is discussed. There is experimental evidence that the superficial oxidation effects are associated, in each material, to the testing temperature, to the duration of the test and to the degree of deformation reached. The influence of the oxidatio is related to the acting deformation mechanisms. The possible corrosion action on the characteristics of the mechanical behavior of the materials under creep is analysed. (Author)

Abstract (Portuguese)

Discute-se a manifestacao da oxidacao superficial em ensaios de ruptura por fluencia realizados com tres acos inoxidaveis austeniticos, executados sob carga constante em fornos abertos a atmosfera entre as temperaturas de 550 e 8000C. A evidencia experimental mostra que os efeitos superficiais da oxidacao sao em cada material associados a temperatura de ensaio, ao tempo de duracao e ao nivel de deformacao atingido. A influencia da oxidacao e relacionada aos mecanismos de deformacao atuantes. Analisa-se a possivel acao da corrosao sobre os indices caracteristicos do comportamento mecanico dos materiais em fluencia. (Autor)
