How Nickel-Based Superalloy AM Works: Solidification and Heat Treatment Basics
Nickel-based superalloy additive manufacturing, exemplified by IN939, relies on layer-by-layer deposition in powder bed fusion systems, where a high-energy beam melts metal powders to form solid structures. The process begins with spreading a 50-100 µm layer of spherical IN939 powder (achieved via gas atomization for <1% oxygen content), followed by selective melting using lasers (200-1000W) or electron beams (up to 60kW). Solidification occurs rapidly, at rates of 10^6 K/s, creating fine microstructures with γ’ precipitates that enhance creep resistance at 950°C. For USA B2B applications, understanding this is vital, as improper parameters lead to epitaxial growth and columnar grains, causing anisotropy—tensile strength varying 15% along build direction. Heat treatment follows: solution annealing at 1160°C dissolves segregations, followed by aging at 870°C for 16 hours to precipitate strengthening phases, as per AMS 5666 standards. Metal3DP’s powders, optimized for SLM and EBM at https://met3dp.com/metal-3d-printing/, show 98% density post-treatment, per our lab data from 2023 trials.
