Thermodynamically-consistent phase-field models for solidification
S. L. Wang,Robert F. Sekerka,A. A. Wheeler,Bruce T. Murray,Sam R. Coriell,Richard J. Braun,Geoffrey B. McFadden +6 more
TL;DR: In this article, a class of phase-field models for crystallization of a pure substance from its melt are presented, which are based on an entropy functional, and are therefore thermodynamically consistent inasmuch as they guarantee spatially local positive entropy production.

EBSD analysis of evolution of dynamic recrystallization grains and δ phase in a nickel-based superalloy during hot compressive deformation
Yong-Cheng Lin,Dao-Guang He,Ming-Song Chen,Xiao-Min Chen,Chun-Yang Zhao,Xiang Ma,Zhi-Li Long +6 more
TL;DR: In this paper, the evolution of dynamic recrystallization (DRX) grains and δ phase, as well as the interactions between DRX grains and the phase were investigated.
Journal ArticleDOI
A quantitative and thermodynamically consistent phase-field interpolation function for multi-phase systems
TL;DR: In this article, a new type of interpolation function is introduced that has a zero slope at the equilibrium values of the nonconserved field variables representing the different phases and allows for a thermodynamically consistent interpolation of the free energies.

Coarsening and dissolution of γ′ precipitates during solution treatment of AD730™ Ni-based superalloy: Mechanisms and kinetics models
TL;DR: In this article, the authors developed a semi-analytical model to describe the dissolution and coarsening processes of the Ni-based superalloy, AD730, and the results from the proposed models, supported by electron microscopy observations, indicate that dissolution occurs before complete dissolution.

Constitutive modeling of the creep behavior of single crystal superalloys under non-isothermal conditions inducing phase transformations
TL;DR: In this paper, the microstructure changes of Ni-based single crystal superalloy are modeled in the framework of crystal plasticity using a macroscopic approach to account for the transient viscoplastic behavior induced by microstructural changes.
