| Contents | The course deals metallic materials fabrication processes with particular attention to iron based alloys production. Starting from chemical physics principles, the ladle furnace and electric furnace processes will be deeply analyzed, with emphasis to the material properties achievable by them. |
| Reference texts | Teaching material including lecture slides, texts and solutions to the proposed exercises, tables, videos and more is available through the Unistudium platform. |
| Educational objectives | The teaching contributes to train the student on the methodological-operational aspects of engineering sciences in general and mechanical engineering in particular: It provides: 1. knowledge inherent in the production processes of metallic materials 2. ability to choose the process based on the properties of the material. |
| Prerequisites | In order to understand and apply most of the concepts in teaching, preliminary knowledge of basic chemistry and physics is required. |
| Teaching methods | The course is organized in classroom lectures during which the topics covered in the course are addressed. All the teaching material used during the course – e.g. lecture slides, exercises completed and proposed, tables, videos and other content – is available through the Unistudium platform. |
| Other information | Further information is available through the Unistudium page of the course. The teacher is available for consultations at the end of each lesson; consultations with the teacher in person or through the Microsoft Teams platform can also be arranged at other times. |
| Learning verification modality | The exam consists of an oral test aimed at verifying knowledge of the topics covered. |
