RECENT PROGRESS IN OXIDE-DISPERSION-STRENGTHENED (ODS) ALLOYS PRODUCED BY ADDITIVE MANUFACTURING

Original language description

Oxide-dispersion-strengthened (ODS) alloys exhibit exceptional mechanical properties, making them ideal for high-temperature applications in areas such as aerospace and nuclear reactors. The traditional manufacturing of ODS alloys involves mechanical alloying, followed by processes such as hot extrusion and hot isostatic pressing. However, these methods are limited when it comes to producing complex geometries. Recent advances in additive manufacturing (AM) techniques, specifically selective laser melting (SLM) and directed-energy deposition (DED), offer exciting new possibilities for fabricating ODS alloys. Early research demonstrated the feasibility of using SLM to create complex parts with uniformly dispersed oxide particles, thereby enhancing the materials&apos; properties. Subsequent studies confirmed that optimising the SLM parameters could further improve the mechanical performance of ODS alloys. DED techniques have also shown promise, with innovations like in-situ oxide formation during deposition and high-speed laser cladding. These methods have achieved success by producing ODS materials with refined microstructures and enhanced mechanical properties. The latest research continues to explore the potential of AM for ODS alloys, focusing on improving the dispersion of nanoparticles and minimising the tendency of particles to agglomerate. Overall, AM has advanced the fabrication of ODS alloys by offering efficient production routes and the ability to create intricate designs with superior properties.
