Quantification of Microstructural Heterogeneities in Additively Manufactured and Heat-Treated Haynes 282
Abstract
Haynes-282 is a gamma prime (γ’) strengthened Ni-based superalloy with excellent high temperature mechanical properties for applications, e.g., in industrial gas turbine engines. Excellent thermal stability ( ̴760 ⁰C) and weldability make this alloy a promising candidate for the manufacturing of near-net shaped parts via electron beam melting (EBM) powder bed fusion (PBF) processes. To enable industrial application of EBM-deposited Haynes-282 components, a systematic understanding of its process-structure-property space is required.<br/><br/>In this study, we used a multi-scale characterization approach to evaluate the impact of variations in EBM process parameters such as scan velocity, build height and, column thickness on size and morphology evolution of γ’, matrix gamma (γ) grains, and carbides in EBM Haynes-282. Microhardness testing was used to understand the effect of microstructural variations on mechanical properties. Further, the effect of post-process heat treatment (testing both a two-step and a one-step ageing process) on microstructure and mechanical hardness was evaluated.
