A viewpoint from dissipative dynamics on diffusion-controlled directional solidification
Fengyi Yu
The existing theoretical analyses of solidification dynamics lack the insights of historical relevance and transport processes in the whole system. Through the phase-field model, t…
The influence of anisotropy on the evolution of interfacial morphologies in directional solidification: A phase-field study
Fengyi Yu
By adjusting the interface energy, curvature, and velocity, the anisotropy plays an important role in the interaction between interfacial processes and transport processes, determi…
The criterion of planar instability in alloy solidification under varying conditions: A viewpoint from free energy
Fengyi Yu
In alloy solidification, the transport processes of heat and solute result in morphological instability of the interface, forming different patterns of solidification structure and…
The effect of the interface energy on pattern selection in alloy solidification: A phase-field study
Fengyi Yu, Qiaodan Hu, Jianguo Li
A thorough understanding of pattern selection is necessary for the control of solidification structures, which are dissipative structures created by irreversible processes. In this…
The role of solute concentration in interface instability during alloy solidification: A viewpoint from the free energy
Fengyi Yu, Qiaodan Hu, Jianguo Li
Solidification structures are determined by the interaction between the interfacial processes and transport processes of heat and solute. In this paper, we investigate planar insta…
Microstructure evolution under the space-time variational solidification conditions in a melt pool: A multi-scale simulation study
Fengyi Yu, Yanhong Wei, Qiaodan Hu +1
The properties of welded components are dominated by the microstructure evolution in the pool, where the solidification conditions are space-time variational. To represent the vari…
