Carpenter Technology Corporation focuses on developing and commercializing novel Ni- and Co-base superalloys for mission-critical applications and exploring new additive manufacturing processes. This presentation reviews three novel high-temperature materials that deliver superior performance and provide end users more design flexibility for increasingly challenging operating conditions:• A novel cost-effective conventional cast-and-wrought \\947;’-Ni₃(Ti,Al)-strengthened Ni-base superalloy with improved forgeability and enhanced tolerance to damage providing a new alternative to existing high-temperature superalloy materials.• A crack-free high \\947;’-Ni₃(Ti,Al) volume fraction Ni-base superalloy for additive manufacturing that enables direct printing of turbine parts with complex internal structures and represents an alternative solution to crack-prone CM 247 LC\\174;.• A family of Co-Ni-base \\947;’-Co₃(Al,W) strengthened superalloys, manufactured through cast-and-wrought processing or additive manufacturing, with improved oxidation and sulfidation resistance and high-temperature strength levels similar to conventional nickel-base superalloys.
