Constrained Grain Boundary Diffusion in Thin Copper Films

Approximate solution of laminar thermal boundary layer over a thin plate heated from below by convection

In this paper, an integration of a symbolic power series method - Padé approximation technique (PS - Padé), was utilized to solve a system of nonlinear differential equations arising from the similarity solution of laminar thermal boundary layer over a flat plate subjected to a convective surface boundary condition. As both boundary conditions tended to infinity, the combination of series solut...

Coercivity enhancement of Nd-Fe-B sintered magnets by grain boundary modification via reduction-diffusion process

The interface between the Nd2Fe14B particles and the grain boundary surrounding them in Nd-Fe-B sintered magnets was modified by diffusion Dy metal selectively through the grain boundary involving the reduction of Dy2O3 or DyF3 with CaH2 and the coercivity of them was effectively enhanced from 0.98 MA/m to 1.42 MA/m with keeping the high value of remanence. The resultant coercivity was higher t...

On Diffusion-Induced Grain-Boundary Motion

We consider a sharp interface model which describes diffusioninduced grain-boundary motion in a poly-crystalline material. This model leads to a fully nonlinear coupled system of partial differential equations. We show existence and uniqueness of smooth solutions.
