A general mechanism of grain growth ─Ⅰ. Theory

Journal of Materiomics, 2021
The behaviors of grain growth dominate the formation of the microstructure inside polycrystalline materials and thus strongly influence their practical performances.

Why grain growth is not curvature flow. [PDF]

Proc Natl Acad Sci U S A
Grain growth in polycrystals is traditionally considered a capillarity-driven process, where grain boundaries (GBs) migrate toward their centers of curvature (i.e., mean curvature flow) with a velocity proportional to the local curvature (including extensions to account for anisotropic GB energy and mobility). Experimental and simulation evidence shows

Reconciling grain growth and shear-coupled grain boundary migration

Nature Communications, 2017
Conventional grain growth models assume the velocity of a grain boundary is proportional to its curvature but cannot account for the many deviations observed experimentally.

Tailoring sintering-resistant thermal barrier coatings by considering critical healing width of two-dimensional interlamellar pores

Journal of Advanced Ceramics, 2023
Large degradation in thermal insulation and strain tolerance is a main headache and a primary cause of the failure for plasma-sprayed thermal barrier coatings (TBCs) during service.

Preparation of Sm0.2Ce0.8O1.9 electrolytes via the chitosan templating method and investigation of the sintering behavior

Journal of Asian Ceramic Societies, 2021
Sm0.2Ce0.8O1.9 electrolytes were prepared using a novel chitosan templating method. To examine the sintering kinetics of the materials, 5 minutes, 1 hour, and 6 hours of sintering processes were carried out at 1200, 1300, and 1400 ⁰C. The phase structure
