Description

Short description:
Explore remelting processes like ESR and VAR and their impact on the purity, structure, and performance of ultra-high strength steels.

Long description:
This module examines remelting processes used to enhance the quality and performance of ultra-high strength alloy steels. It focuses on Electro Slag Remelting (ESR) and Vacuum Arc Remelting (VAR), explaining their role in reducing inclusion content and improving material purity. The module explores how these processes influence mechanical properties such as toughness, ductility, fatigue life, and isotropy. It also addresses the effects of chemical composition, segregation, and retained austenite, including methods for detecting and mitigating related risks. Learners will analyze how processing routes and heat treatment practices contribute to achieving specified mechanical performance in critical applications.

What you will learn
