# Advanced metallurgy

## Summary

This course covers advanced metals and alloys both in terms of specific alloy classes (e.g. Ni-base, Ti-base, precious metals, High Entropy alloys, Metallic glasses) as well as general concepts (e.g. electrical and thermal properties, general characteristics of metallic melts and solids).

## Content

The course's goal is to enlarge the field of knowledge of students beyond the classical three metals and alloy classes (i.e. iron and steel, aluminium, copper and their alloys) and to deepen the understanding of general characteristics of metals and alloys both in the liquid and in the solid state. In particular the technological important classes of Ni-base, and Ti-base alloys will be discussed allong with precious metal metallurgy and intermetallics and also touching on some of the more modern developments e.g. metallic glasses and high entropy alloys. Special purpose metallic materials will be treated as well. The students will be introduced to hands-on thermodynamical stability calculations involving (solid) solutions, including potential reactions with crucible material or reinforcements in composite materials. Another purpose is to install the capacity to estimate certain properties based on a set of rules of thumb and knowledge of the phase diagram of the system at hand. Some quantitative models based on electronic theory (e.g. phase stability, heat of mixing) will be discussed as well.
