L-PBF Process Development & Parameter Optimization for ODS Alloys

The contract seeks to develop and optimize laser powder bed fusion parameters for oxide dispersion strengthened nickel-based alloys with the goal of achieving a relative density of at least 99.9 percent while ensuring superior high-temperature performance. This effort is focused on refining process variables such as laser power, scan speed, hatch spacing, and layer thickness to overcome the unique challenges posed by ODS alloys, including their high melting points and complex microstructural requirements. The objective is to produce defect-free, fully dense components capable of sustaining extreme thermal and mechanical loads typical of aerospace propulsion and power generation systems. The work is being undertaken as a subcontract under the NASA Shared Services Center, with a response deadline of May 15, 2026, and an official posting date of May 12, 2026. The North American Industry Classification System code 332999 indicates a focus on miscellaneous fabricated metal product manufacturing, aligning with advanced additive manufacturing activities. While no specific place of performance or point of contact is provided, the endeavor is part of NASA’s broader strategy to enable next-generation high-performance materials through additive manufacturing, with direct applications in next-generation turbine components and spaceflight systems requiring extreme reliability under challenging operational environments.
