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 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...

متن کاملOn 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 ...
