Multi-Scale Characterization of Different Generations of Gamma Prime Precipitates in Nickel-based Superalloys Using Correlative Microscopy Techniques
Nickel-based superalloys have been widely used for elevated temperature applications such as turbine disc of jet engines due to their excellent mechanical properties. The typical microstructure of these alloys primarily consists of dispersed precipitates of the ordered γ’ phase with L12 structure within a disordered face-centered cubic γ matrix. The γ -γ’ microstructure in these alloys can be c...
متن کاملStrain induced abnormal grain growth in nickel base superalloys
Under certain circumstances abnormal grain growth occurs in Nickel base superalloys during thermomechanical forming. Second phase particles are involved in the phenomenon, since they obviously do not hinder the motion of some boundaries, but the key parameter is here the stored energy difference between adjacent grains. It induces an additional driving force for grain boundary migration that ma...
متن کاملResidual Stress Assessment in Surface-treated Nickel-base Superalloys
Experimental results are presented to illustrate that there exists a unique window of opportunity for eddy current NDE of residual stress in surface-treated nickel-base superalloys. In light of its frequency-dependent penetration depth, the measurement of eddy current conductivity has been suggested as a possible means to allow the nondestructive evaluation of subsurface residual stresses in su...

متن کاملReview on Thermo-Mechanical Fatigue Behavior of Nickel-Base Superalloys
Nickel-base superalloys have become the key materials of hot-end components in the aeroengines over the past several decades. Nickelbase superalloys are easy to produce thermo-mechanical fatigue (TMF) behavior when withstanding the combined effects of high temperature, creep, oxidation, mechanical stress and thermal stress. The occurrence of TMF seriously affects the normal service for hot-end ...
