The unit focuses on metals and metal-based materials as well as metal alloys. The iron-carbon phase diagram is studied in detail as it helps to understand the difference between steel and cast iron – two alloys, which are very widely used in day-to-day life. Practical exercises teach how to obtain some alloys and analyze them with different techniques including differential scanning calorimetry – a method that gives information about the phase transitions of a material under temperature change. Upon completion of this course, students acquire knowledge directly applicable to the industry.
