In this study, a Hastelloy C276 thin-wall structure was fabricated by wire arc additive manufacturing (WAAM). The microstructure and mechanical properties of the as-deposited were evaluated in detail using specimens extracted from different orientations locations along deposition direction. results show that primary dendrite arm spacing, dislocation density, second-phase precipitates change direction material, they are responsible for occurrence anisotropy heterogeneity observed properties....
Abstract By time-of-flight (TOF) neutron diffraction experiments, the influence of segregation-induced microstructure bands austenite ( γ ) and martensite α′ phases on partitioning stress strain between these was investigated. Initially, tensile specimens a Co-added stainless steel were heat treated by quenching (Q&P) processing. Tensile subsequently loaded at 350 °C parallel to length within apparent elastic limit phase mixture. Lattice parameters in both axial transverse directions...
Relatively high heat input and accumulation are treated as critical challenges to affect the qualities performances of components fabricated by wire arc additive manufacturing (WAAM). In this study, various inputs, namely 276, 552 828 J/mm, were performed fabricate three thin-wall Inconel 625 structures cold metal transfer (CMT)-based WAAM, respectively, active interpass cooling was conducted limit accumulation. The macrostructure, microstructure mechanical properties produced CMT...
A new structure with nickel-based Hastelloy C276 alloy cladding on creep resistant steel P91 was developed in this study for nuclear applications. The microstructure, including precipitation and grain size, boundaries, orientation hardness distribution of structures with/without post heat treatment were explored using a range microscopy techniques testing. results show that the as-cladded exhibits highly hierarchical heterogeneity, which is mainly related to remarkably coarse-grained...
