This study is focused on a critical evaluation of the features and properties of thick ferrule usually applied for construction of reactors and realized through different technological routes. At the present these pieces can be obtained through three different technological routes: forging, hot rolling and cold bending. The characterization of the analysed ferrules has been performed through the coupling of results coming from metallographic optical observations, mechanical tests, texture crystallographic analysis performed by SEM-EBSD. The obtained results allow defining the mechanical performances as a function of the applied technology and they permit comprehending these results on the basis of the particular micro-structural modifications induced by the investigated processes and the examined production systems.

Abstract
This study is focused on a critical evaluation of the features and properties of thick ferrule usually applied for construction of reactors and realized through different technological routes. At the present these pieces can be obtained through three different technological routes: forging, hot rolling and cold bending. The characterization of the analysed ferrules has been performed through the coupling of results coming from metallographic optical observations, mechanical tests, texture crystallographic analysis performed by SEM-EBSD. The obtained results allow defining the mechanical performances as a function of the applied technology and they permit comprehending these results on the basis of the particular micro-structural modifications induced by the investigated processes and the examined production systems.File | Dimensione | Formato | |
