On August 10, 2026, Xi'an Aerospace Intelligent Manufacturing (a national-level "Little Giant" specialized and innovative enterprise) teamed up with Professor Chen Kai's team at Xi'an Jiaotong University to successfully achieve high-quality, stable forming of DZ125 and DD6 nickel-based superalloys—both highly crack-sensitive materials—using their self-developed M100 electron beam selective melting (EBSM) equipment. The core technology lies in a synergistic control pathway of "high-temperature preheating, melt pool morphology regulation, and scanning strategy matching": a discrete, fixed-point melting scanning approach replaces conventional continuous line scanning, allowing precise control of electron beam melt pool energy. Validation through CT non-destructive testing, metallographic observation, and EBSD grain structure analysis confirmed that the specimens are free of internal cracks, porosity, lack-of-fusion, and other metallurgical defects, with the ability to achieve directed columnar or equiaxed grain growth as required. DZ125 and DD6 are critical materials for hot-section components such as aircraft engine turbine blades and are widely recognized in the industry as "unweldable" nickel-based superalloys. Traditional precision casting relies on mold cores and suffers from low yield rates, while laser additive manufacturing faces large temperature gradients and difficult-to-control thermal cracking. This breakthrough provides a new domestic solution for manufacturing integrated aviation hot-section components with thin walls, hollow structures, and multiple cooling channels. The transition from "unweldable" to "high-quality forming" signals that additive manufacturing is challenging the irreplaceable position of traditional casting in the core hot-section components of aircraft engines. Value for powder buyers: ① DZ125/DD6 powders are high-value-added, aviation-grade superalloy powders; while current annual domestic demand is limited (hundreds of tons), unit prices far exceed those of conventional nickel-based powders. ② The EBSM breakthrough opens new possibilities for powder metallurgy routes to replace precision casting; if scaled to engineering application, it will drive demand for directionally solidified/single-crystal superalloy powders like DZ125/DD6. ③ These specialty powders require extremely high sphericity and purity during production (via PREP or EIGA), and only a few manufacturers have the capability, making this a high-barrier niche market.
