Program Overview
This expert-led program focuses on the precision, complexity, and criticality of heat treatment processes in the aerospace sector. Participants will gain a strong foundation in thermal processing techniques—including annealing, hardening, aging, nitriding, and vacuum heat treatment—for both ferrous and non-ferrous alloys. The course also emphasizes compliance with aerospace-specific standards such as AMS 2750, AMS 2759, and NADCAP. Through real-world aerospace case studies (e.g., landing gear, turbine shafts, engine blades), the course enables professionals to diagnose heat treatment failures, prevent distortions, and optimize mechanical performance. Simulations and audit-readiness drills prepare participants to align with global benchmarks in aerospace quality and safety.
