The anisotropic oxidation behavior of Hastelloy X alloy fabricated by laser powder-bed fusion (LPBF) during the cyclic oxidation process
Source abstract
Abstract
The Hastelloy X alloy manufactured via LPBF has anisotropic oxidation behavior at 900 °C. The vertical cross section (V) specimen has worse oxidation resistance and more severe spalling behavior than the horizontal cross section (H) specimen as its low grain boundary density. During the oxidation process, larger voids was generated at Cr 2O 3 -spinel interface of the V specimen to weaken the adhesive strength of oxidation film, and α-NiMoO 4 with high cracking susceptibility only occurred in spinel layer of the V specimen, which broke down under high compressive stress in oxidation film to promote the spalling of oxides.
