An investigation into cracking in nickel-base superalloy repair welds [PDF]

, 2010
The nickel-base superalloy Rene 80 is considered very susceptible to liquation and strain-age cracking. Material in the solutionised condition is welded using the Cold Metal Transfer, or CMT process (with ductile filler alloy) and autogenously using a

Surface Microstructure of Nanoaluminized CoCrAlY Coating Irradiated by HCPEB

Journal of Nanomaterials, Volume 2016, Issue 1, 2016., 2016
A thermal sprayed CoCrAlY coating was prepared by air plasma spray on the surface of Ni‐based superalloy GH4169; then, a nanoscale aluminum film was deposited with electron beam vacuum deposition on it. The coatings irradiated by high‐current pulsed electron beam were investigated. After HCPEB treatment, the Al film was remelted into the bond coat. XRD

Performance of two different constitutive models and microstructural evolution of GH4169 superalloy

Mathematical Biosciences and Engineering, 2019
The hot compression tests of GH4169 superalloy were performed in the deformation temperature range of 970 to 1150 ℃ and at the strain rate range of 0.001 to 10 s⁻¹. The flow stress is dependent on temperature and strain rate. The flow stresses were respectively predicted by Arrhenius-type and artificial neural network (ANN) models, and the predicted ...

Machine Learning‐Assisted Sensitivity Analysis for Stochastic Fatigue Life Modeling of Metals

International Journal of Mechanical System Dynamics, Volume 5, Issue 3, Page 481-494, September 2025.
ABSTRACT Predicting fatigue life with precision requires more than isolated evaluations of mechanical properties; it requires an integrated approach that captures the interdependencies between various parameters, including elastic modulus, tensile strength, yield strength, and strain‐hardening exponent.

Numerical Simulation of Creep Damage and Life Prediction of Superalloy Turbine Blade

Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015
Creep caused failure is an important failure mode of the turbine blade. A numerical approach of life assessment of the superalloy turbine blade is proposed in the present paper based on the Lemaitre‐Chaboche creep damage model. Material damage is introduced into each element based on the ANSYS APDL function, and the creep damage effect is considered ...

Effects of Shot‐Blasting and Induction Hardening on the Fatigue Strength of Hot‐Forged Wheel Bearing Hubs

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 8, Page 3353-3367, August 2025.
ABSTRACT Hot‐forged wheel bearing hubs are manufactured using a complicated fabrication process chain to obtain the desired microstructure and mechanical properties in different zones that experience varying local stress states. The different process steps modify the surface roughness and the residual stresses distribution and therefore affect the ...
