20/11/2020: How to read a phase diagram I

Metallic systems

Phase diagrams are graphical representations of materials, most commonly as a function of temperature and composition. In this “how to read a phase diagram” course the main focus is on the practical aspects of reading. It gives an insight into the type of information you can retrieve from a phase diagram and how to give an interpretation to the different lines and areas in the graph. The course starts with a basic level introduction but rapidly advances to more complex systems. Exercises are foreseen to ensure a thorough understanding. Exercises in this first part focus mainly metallic material systems (alloy melting points, solidification, heat treatment, precipitation, etc.), with special attention to iron and steel. A next session focuses on specific diagrams for oxides and sulphides (slag and matte).

Aim

After the course all participants know how to interpret a phase diagram and are able to use it in industrial applications.

Method

The course will tackle the theory of the topics listed above and several exercises will be made to ensure that everything was understood. It is advisable to bring a pencil, ruler, and calculator.

Who should attend

The course will be given in English and aims at people active in the metal processing industry. The course can be a refreshment of the metallurgical principles for engineers, or give hands-on metallurgists a solid theoretical background.
