The process of microstructural characterization of stainless steel Austenitic - ferritic structure by means of Metallographic replica

摘要

b process of microstructural characterization of stainless steel of structure of austenitic ferritica through Metallographic replica d , the present invention relates to a process for microstructural characterization of stainless steel Austenitic - ferritic structure by means of a replica met Alogru00e1fica, used as a nondestructive tool for the inspection of pipes and equipment.The application of this technique to characterize the fragilizantes precipitated phases, as well as the size and proportions of the phases present in the microstructure, in view of the conditions required by the standards established in the project of construction of these components of the process.
