Abstract Scope A high-throughput micro-synthesis method is developed to study the Ni-based superalloys based on the powder metallurgy sintering approach. A honeycomb array sleeve is made by additive manufacturing firstly, then filled with powder mixture via combinatorial design, densified by hot-isostatic-pressing (HIP) process, homogenized with high temperature heat treatment, and finally prepared a combinatorial superalloy library with more than 80 various chemical compositions. Centered on a base superalloy, the compositions of Co, Ta and Nb are designed to form 6 superalloy groups. This combinatorial superalloy is characterized by LIBS, micro-XRF, Full-view-metallography, SEM, micro-XRD and micro hardness etc. The effects of chemistry on microstructure and property are studied. This work put forward a new high throughput HIP micro-synthesis approach for accelerating the design and screening of superalloys.
