Metallurgy basics

The  course clarifies the microstructure, properties and  engineering applications of metallic alloys in the most significant fields ( for example aerospace, automotive, civil, structural,  biomedical).

After the course the students:

1)  will know the various types of major engineering alloys in term of microstructure, properties and applications

2) will be able to make decision for material selections for engineering design

3) will know the strengthening method, heat treatments and surface hardening/ modifications to apply with regard the required service properties   

Lectures, laboratory practice, individual project

The exam consists of two parts:

1. first written part: the student is asked to illustrate theoretical topics
2. second part: the student is asked to discuss the laboratory topics and  individual project with the lecturer.
