Microstructural Modeling During Multi-Pass Rolling of a Nickel-Base Superalloy
Superalloys are metallic alloys used for high temperature applications such as encountered in the aircraft industry and where resistance to deformation is a primary requirement. Alloy 718 and waspaloy are few examples of Nickel-base superalloys that resist deformation at elevated temperatures and are therefore difficult to hot work. The major hotworking operations are forging, extrusion, and ro...
متن کاملEffect of Heat Treatment Process on Microstructure and Fatigue Behavior of a Nickel-Base Superalloy
The study of fatigue behaviors for nickel-base superalloys is very significant because fatigue damage results in serious consequences. In this paper, two kinds of heat treatment procedures (Pro.I and Pro.II) were taken to investigate the effect of heat treatment on microstructures and fatigue behaviors of a nickel-base superalloy. Fatigue behaviors were studied through total strain controlled m...

متن کاملDesign 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 ...
متن کاملPhase-field Modeling with CALPHAD and CVM for Microstructural Evolution of Ni-base Superalloy
To perform a quantitative simulation using the Phase Field Method (PFM) in a real alloy system, a new strategy of modeling the microstructure evolution of Ni-base superalloy is proposed in the present paper. In this strategy, the Calculation Phase Diagram (CALPHAD) method and Cluster Variation Method (CVM) are combined with the PFM, in which the four sub-lattice model is used to evaluate the fr...
