متن کاملDeformation Mechanisms in Ni-base Disk Superalloys at Higher Temperatures
This paper presents results from a research initiative aimed at investigating high temperature creep deformation mechanisms in Ni-base superalloys through a combination of creep experiments, TEM deformation mechanism characterization, and state of the art modeling techniques. The effect of microstructure on dictating creep rate controlling deformation mechanisms was revealed for specimens with ...
متن کاملModelling the creep anisotropy of nickel-base superalloys with a composite model
The creep anisotropy of nickel-base superalloys with a cubic y' morphology is studied with a composite model. Creep curves and the internal stress distribution in the microstructure under [Oll] load are calculated with a Finite Element Procedure. Analytical considerations are made for arbitrary loading directions. y' cubes (with their interfaces aligned parallel to (001) planes) under [OOl] loa...
متن کاملControlling the Deformation Mechanism in Disk Superalloys at Low and Intermediate Temperatures
The newly developed TMW disk superalloy exhibits better overall mechanical properties in the intended service temperature region (650-750 °C) than the most advanced cast & wrought disk alloy U720Li. Clarification of the underlying mechanisms is beneficial for designing advanced superalloys. Among the TMW alloys, TMW-4M3 has the best tensile strength and creep resistance. In this study, tensile ...
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...
