A method for increasing the supersolvus critical strain for recrystallization in single-crystal superalloys

open access: yesMaterials Research Letters, 2023
Recrystallization, possibly triggered during heat treatments by plastic strains of only 1–2%, is highly deleterious to Ni-based single-crystal superalloys.

Application of Hot Isostatic Pressing in Nickel-Based Single Crystal Superalloys

open access: yesCrystals, 2022
Hot isostatic pressing (HIP) technology can effectively reduce microstructure defects such as micropores, which are formed during solidification and hominization heat treatment, and thus further improve the high temperature performance of nickel-based SX

Composition rules of Ni-base single crystal superalloys and its influence on creep properties via a cluster formula approach. [PDF]

open access: yesSci Rep, 2020
The present work investigated the composition evolution of the TMS series of Ni-base single crystal (SC) superalloys in light of the cluster formula approach systematically. The cluster formula of SC superalloys could be expressed with [Al¯-Ni¯12](Al¯,Cr¯

Topologically inverse microstructure in single-crystal superalloys: microstructural stability and properties at ultrahigh temperature

open access: yesMaterials Research Letters, 2021
Topological phase inversion, in which γ'-precipitate becomes topological matrix phase, is a typical ‘detrimental’ microstructural degradation in Ni-based single-crystal superalloys.
