Questo lavoro di tesi aveva come obiettivo la caratterizzazione meccanica e il confronto tra diversi tipi di acciaio, in particolare sono stati analizzati due acciai per impiego strutturale e quattro acciai automatici. Le prove meccaniche effettuate sono state scelte per ottenere le principali caratteristiche di resistenza meccanica, mentre le analisi chimiche e metallografiche sono servite per comprenderne la loro composizione e le strutture presenti. È quindi stato possibile confrontare i risultati ottenuti dai differenti materiali e gli effetti portati dall’aggiunta di elementi chimici necessari per conferire attitudini tecnologiche completamente diverse.

Abstract
This thesis work had as objective the mechanical characterization and the comparison between different kind of steels, in particular two structural steels and four free-cutting steels have been analysed. The mechanical tests performed have been chosen in order to retrieve the principal mechanical properties, while the chemical and metallographic analysis allowed to understand their effective composition and which structures were present. At the end, it was possible to compare the results obtained from different material and the effects derived from the addition of chemical elements, that have to provide to these materials completely different technological attitudes.File | Dimensione | Formato | |
