Symposium Advanced Characterization of High-temperature Alloys: Phase Evolution during Manufacturing and Service-induced Deformation
Presentation Title Phase-Field Modeling of Rafting in Ni-Based Superalloys with a Varying Lattice Misfit
Author(s) Jose Dominic, Jean-Briac le Graverend
On-Site Speaker (Planned) Jose Dominic
Abstract Scope Phase-field modeling for rafting in Ni-based superalloys commonly uses a constant lattice misfit, namely the natural lattice misfit. However, in reality, the lattice misfit is a constrained lattice misfit that evolves. A varying lattice misfit is implemented in a phase-field model and the effects on the rafting process are investigated during creep at 1100C.
