Metallographic Study on Alloy Zircaloy-4 of Nuclear Use

In this paper we present the results metallographic examination of Zry-4 used in the manufacture of miniplates. The metallographic characterization was performed in order to know the microstructures and microhardness of thereof. These analysis have been carried out for different stages of hot co-rolling, and have been analyzed changes produced in the welding process (method: TIG) to determine in the miniplate if the temperature generated in this stage of manufacture produce changes in the microstructure and microhardness in different areas, from edge to core
