Description of Spherical Inconel 738 Powder
Inconel 738 is composed primarily of nickel (Ni), with significant amounts of chromium (Cr), cobalt (Co), and molybdenum (Mo), as well as smaller quantities of aluminum (Al), titanium (Ti), and other elements.
Spherical Inconel 738 powder is a high-performance, nickel-based superalloy commonly used in applications that require excellent mechanical strength, oxidation resistance, and high-temperature stability. The alloy, designated under the Unified Numbering System (UNS) as N07738, is specifically engineered for use in environments that demand long-term service at elevated temperatures, such as in gas turbine engines and other aerospace components.

Spherical inconel 738 Powder Reference
- This study reports the successful crack-free fabrication of the non-weldable high γʹ Ni-superalloy IN 738 by laser powder bed fusion. The as-fabricated texture was composed of columnar grains with preferred orientation along <100> direction. Scanning electron microscopy and X-ray diffraction analysis revealed the presence of M(Ti, Ta, W, Mo, Nb)C and M(Cr, Mo, W)23C6 carbides along the grain boundaries.
Inconel 718 powder is typically produced through gas atomization, where molten Inconel 718 is atomized into fine droplets using high-pressure gas, resulting in spherical powder particles. Other methods include plasma atomization and the Plasma Rotating Electrode Process (PREP), both of which also produce high-purity, spherical powders ideal for additive manufacturing. These processes ensure the powder has excellent flowability, making it suitable for 3D printing and high-performance applications.
Inconel 738 powder is primarily produced through gas atomization, where molten Inconel 738 is broken into fine droplets using high-pressure gas, which then solidify into spherical particles. Plasma atomization is another method, offering high-purity, uniformly spherical powders suitable for additive manufacturing. These methods ensure the powder’s consistency and performance for high-temperature applications, such as in aerospace and turbine components.
