Program Overview
This expert-led program offers a deep-dive into the science, techniques, and real-world application of industrial heat treatment processes. It equips professionals with practical knowledge of annealing, hardening, tempering, case hardening, and surface treatment methods across ferrous and non-ferrous materials. Participants will explore phase transformations, defect prevention, and furnace control strategies to improve mechanical properties like hardness, toughness, and wear resistance. Through real-life case studies and hands-on simulations, the course helps engineers optimize heat treatment cycles, reduce failures, and enhance part performance across industries such as automotive, aerospace, tooling, and heavy manufacturing.
