A design for preparation of textured piezoelectric ceramics based on the phase-field simulation
Journal of Advanced Dielectrics, 2022 To solve the problem of directional arrangement of small template particles, we designed a lamination technique for the preparation of dense ceramics with high texture degree based on the phase-field simulation.

Physical Review Letters, 2003 We report the in situ investigation of grain growth and grain boundary migration, performed with a variable-temperature scanning tunneling microscope (STM) on a polycrystalline gold film. Atomic step resolution allowed us to identify the individual grains and, thus, also the grain boundaries.

On the Grain Growth Kinetics of a Low Density Steel
Metals, 2019 The grain growth kinetics of an age-hardenable Fe-Mn-Al-C steel were investigated. Kinetics of grain growth were determined between 1173 and 1348 K (900−1075 °C) to obtain a range of grain sizes from 30 to 475 μm.

FIVE WORDS YOU SHOULD NEVER SAY IN YOUR SALES LETTER [PDF]
, 2008 The theoretical description of grain growth was based for many years on the so-calledspherical model. The spherical model represents a polyhedral grain with N faces and a volume, V ,by a sphere with an equal volume having the equivalent grain radius, R ...

Experimental and Numerical Simulations of the Solidification Process in Continuous Casting of Slab
Metals, 2016 Thermal simulation equipment (TSE) was recently developed to simulate the solidification process in the industrial continuous casting of slab. The grain growth, solid-liquid interface movement, and columnar-to-equiaxed transition (CET) in the continuous ...
