Aubert & Duval has developed an age-hardenable nickel-based superalloy designed specifically for use as feedstock in powder bed fusion. Stellar ABD®-900AM is optimized for high creep and tensile strength, and corrosion/oxidation resistance, with a working temperature range up to 900°C in its age-hardened state. The new alloy has excellent creep strength – similar to alloy 939 and Ni 738 – while having superior resistance to cracking during manufacture and heat treatment. Designed to be free of solidification, liquidation and strain-age cracks, Stellar ABD®-900AM is 40% ɣ’ phase and showcases exceptional printability for such a high temperature strengthened alloy. It is suitable for complex components within the Aerospace, Power, Automotive and Space industries.
