A sample from this course

One topic, as StudyPath teaches it.

Nucleation and grain growth

Nucleation and grain growth govern the micro‑structure of welded metals. Mastering the driving forces, critical sizes, and growth kinetics is essential for predicting weld micro‑structure, mechanical properties, and for controlling defects such as porosity or cracking.
