Microstructural Analysis of the Influence of Ecap on the Pure Nb Rolling Plane
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 3
Abstract
Starting From a sample of pure and pre-deformed niobium by cold rolling a severe plastic deformation process was performed using ECAP (equal channel angular pressing) in order to verify the evolution and distibution of the deformation structures and of hardness in the lamination plane of the material. To make the analysis were used: the Scanning Electron Microscope-SEM, optical microscope and a hardness map to have a better view of how homogeneous or heterogeneous a process is in relation to the other. After comparison it was seen that the process through ecap uniformized the microstructure and hardness of the material.
