Learning nugget: Metallurgical quality
SUMMARY:
Metallurgical quality is an indication of a metal’s nucleation potential, that is, the ease with which carbon precipitates in the form of graphite throughout the solidification process. To determine a metal’s metallurgical quality, solidification and cooling curves are used, obtained through thermal analysis, plotting the metal’s temperature against time. Thermal analysis studies the metal’s behavior throughout the solidification process and its subsequent cooling to room temperature. During solidification, iron castings undergo structural changes, including graphite nucleation, subsequent growth, and changes in the microstructure of the metal matrix. These changes occur throughout the solidification and cooling process and are reflected in the thermal analysis curve.

(*) This training session dedicated to the Metallurgical Quality is part of the “Introduction to Iron Casting” series, which consists of 13 short videos lasting between 15 and 40 minutes.
Language:
English (soon)
Target audience:
- Technical and non-technical staff of iron foundry companies.
- New hires.
“The Foundry of the Future is that of connected processes that is able to take advantage of the knowledge generated inside the company at the same time that it keeps learning from its manufacturing and market experience.
Along with a deep knowledge of metallurgy, Industry 4.0 technologies, advanced data management systems and machine learning technologies have landed in this industry to transform the way castings are conceived”.
