Description
Short description:
Learn how direct hardening alloy steels are selected and processed for large forgings and heavy engineering applications.
Long description:
This module explores the application of direct hardening alloy steels in large forging contexts, focusing on material selection, processing techniques, and performance requirements. It examines low hardenability steels used for large-diameter components, highlighting how hardness gradients and core ductility are achieved through controlled heat treatment. The module also introduces chromium/boron steels in direct quenching applications, including their composition, mechanical properties, and industrial uses. Learners analyse large forging production processes, such as turbine rotor manufacturing, and evaluate the relationship between machining, heat treatment, and final mechanical performance. Practical scenarios support decision-making in selecting materials and processes for heavy engineering applications.
