| Abstract Scope |
Conventional fabrication routes for ODS steels involves production of powder by gas atomization, ball milling, powder vacuum canning, followed by hot extrusion (for rod forms), or hot isostatic pressing, followed by hot cross rolling and cold rolling (for plate forms), with annealing steps often required in-between rolling steps. Such conventional thermomechanical processing (TMP) routes are time consuming, expensive, difficult to scale up, and extremely delicate as cracks can develop and the bulk material can “bend out of shape” during TMP steps. Alternatively, leveraging recent advances in ODS powder production by gas atomization reaction synthesis, i.e., without ball milling, along with severe plastic deformation based yet scalable manufacturing methods collectively called solid phase processing, a new class of ODS steels have been produced. Thanks to the dynamic recrystallization (DRX) concomitant with consolidation and shape forming, these DRX-ODS steels are free of the common microcracks or stringers, leading to excellent fracture toughness. |
