Abstract

SEM and quasi-in situ Micronano-CT were used to evaluate the evolution law of the three-dimensional form and size of Al2O3 inclusions in FGH96 powder metallurgy superalloy during the hot iso-static pressing (HIP), hot extrusion (HEX), and hot isothermal forging (HIF) processes. Quantitative analysis was used to determine how inclusion size changed during several stages, characterise their three-dimensional (3D) morphology, and propose a deformation process [1]. According to the findings, the inclusions in the powder stage had a long stripe or plate-like form. Al2O3 inclusions were mechanically linked to the alloy matrix during HIP, and the matrix's chemical make-up, shape, and size were all left unaltered. Al2O3 inclusions were seen in HEX Shear stress caused the object to break and stretch into a chain shape [2]. The quantitative link between original inclusion size, extrusion ratio, and inclusion size after extrusion was determined. For the first time during HIF, the relationship between a single inclusion's 3D shape, size, orientation, and deformation during forging compression was quantitatively described by quasi in-situ micronano-CT. The aforementioned evolution law offers a conceptual framework and practical support for raising the powder turbine disk's purity level.
