RESUMO

The microalloyed steels have been utilized in several applications: one of these applications is the substitution of the conventional structural steels. As a result of that, it is necessary to improve the relationship between strength and fracture toughness by microstructural optimization, permiting weight saving design. The purpose of this work is to analyze the mechanical properties of a titanium and niobium microalloyed low carbon steel, an API 5L X65, in some microstructural conditions from the thermal treatments: normalization (from 1193 and 1223 K), quenching and austempering from the intercritical annealing (in 1043, 1083, and 1113 K). It was analyzed also the effect of the material anisotropy for the as received condition...Note: The complete abstract is available with the full electronic digital thesis or dissertations
