Preform Conditions for Powder-consolidated Nickel-base Superalloy Mod. IN-100 Aimed at Grain Refinement

On APFIM of Grain Boundaries in a Nickel Base Superalloy

Experimental details of atom probe field ion microscopy (APFIM) of a Ni-16Cr-9Fe alloy are presented. In particular, studies concerning analysis of intergranular carbides and borides and segregation to grain boundaries are described. It was found that NiZ3B6 precipitates are very sensitive to preferential field evaporation, which necessitates optimization of the analysis conditions. In the FIM ...

A Comparison of the Plastic-flow Response of a Powder-metallurgy Nickel-base Superalloy (postprint)

Fatigue Behavior and Life Prediction Model of a Nickel-Base Superalloy under Different Strain Conditions

The fatigue behavior of a nickel-base superalloy was investigated under total strain-controlled mode at high temperature. The fatigue life, cyclic stress response behavior and hysteresis loop of the superalloy were investigated under isothermal low cycle fatigue (LCF) conditions. The superalloy exhibited cyclic hardening and softening behaviors during the process of fatigue loading. The hystere...

Design of a nickel-base superalloy using a neural network

A new computational tool has been developed to model, discover, and optimize new alloys that simultaneously satisfy up to eleven physical criteria. An artificial neural network is trained from pre-existing materials data that enables the prediction of individual material properties both as a function of composition and heat treatment routine, which allows it to optimize the material properties ...
