| Abstract Scope |
Forged components are used in aerospace, automotive, and defense industries due to their superior strength and durability. Forging dies are subjected to severe cyclic stresses, which can cause thermal fatigue, cracking, and wear, ultimately leading to die failure and production delays.
This study presents the application of Arc-based DED techniques for the restoration of damaged forging dies. Diverse alloy repair materials were deposited on H13 tool steel die substrates, comprising iron-based Eureka 450, cobalt-based Eureka MF201, and nickel-based Eureka CWD. A thorough microstructural investigation, microhardness, and mechanical testing validated robust metallurgical bonding and facilitated an accurate assessment of the heat-affected zone adjacent to the interface to check the repair process integrity and reliability. A sharp spike in hardness was observed at the interface due to the formation of intermetallic compounds and untempered martensite during rapid cooling. Nickel-based repair alloys exhibited enhanced toughness and ductility owing to their stable austenitic matrix. |
