Although nickel-based superalloys are widely used in the industry, their response to shock loading is still rarely investigated. Here, impacts of laser-launched flyers were study dynamic behavior a Rene 65 superalloy under pressures about 10 GPa at very high strain rates 6 s −1 . Three types samples, wrought or additively manufactured (laser powder bed fusion) and subjected different heat treat...

Precipitation of γ’ phase in nickel-base superalloy IN792-5A was studied using in-situ Small Angle Neutron Scattering (SANS). It was found that additional precipitates are formed after reheating above 600 ̋C when the material is previously fast cooled (100 K/min) from 900 ̋C. The size distribution and volume fraction of the additional γ’ precipitates as well as of the already present medium-siz...

Recent research results indicate that eddy current conductivity measurements can be exploited for nondestructive evaluation of subsurface residual stresses in surface-treated nickel-base superalloy components. According to this approach, the depth-dependent electric conductivity profile is calculated from the measured frequency-dependent apparent eddy current conductivity spectrum. Then, the re...
