Hybrid Tool Steels Produced Via Hot Isostatic Pressing

Paper in proceeding, 2024

Hybrid tool steels, designed to meet diverse specifications, offer superior fatigue life, toughness, and abrasion resistance. However, this may pose significant challenges in traditional manufacturing. The current study explores the use of Hot Isostatic Pressing (HIP) to bond a high-wear-resistant cold work tool steel powder (Vanadis 8 SuperClean) with a tough hot work tool steel bar (Orvar 2 Microdenodized). The effectiveness of HIP in creating hybrid tool steels is assessed. The impact on the microstructure and mechanical property in terms of hardness in the bonding zone has been examined by employing various analytical methods and simulations. The results confirm a strong bond achieved through HIP, with promising initial outcomes.
