Ultra-large single crystals by abnormal grain growth
Producing a single crystal is expensive because of low mass productivity. Therefore, many metallic materials are being used in polycrystalline form, even though material properties are superior in a single crystal.

Influence of Hot Forging Parameters on a Low Carbon Continuous Cooling Bainitic Steel Microstructure
Thermomechanical processing of low carbon bainitic steels is used to obtain a bainitic microstructure with good strength and toughness by continuous cooling after forging without the need of further heat treating, hence reducing manufacturing costs ...

Grain growth and grain translation in crystals [PDF]
Grain growth is generally driven to minimize the overall grain boundary energy. However, for low-angle grain boundaries the requirement that lattice planes be continuous across the boundary gives rise to a coupling between the normal motion of the grain boundary and the tangential motion of the lattice.

Subgrain-controlled grain growth in the laser-melted 316 L promoting strength at high temperatures [PDF]
Stainless steel 316 L prepared by laser melting consisted of a hierarchical austenitic microstructure with micrometre-sized (10–25 µm) grains containing fine 1 µm subgrains with a cellular structure.

The dust mass in z > 6 normal star forming galaxies [PDF]
We interpret recent ALMA observations of z > 6 normal star forming galaxies by means of a semi-numerical method, which couples the output of a cosmological hydrodynamical simulation with a chemical evolution model which accounts for the contribution to ...

Rotation-limited growth of three dimensional body-centered cubic crystals
According to classical grain growth laws, grain growth is driven by the minimization of surface energy and will continue until a single grain prevails.

Grain charging in protoplanetary discs [PDF]
Recent work identified a growth barrier for dust coagulation that originates in the electric repulsion between colliding particles. Depending on its charge state, dust material may have the potential to control key processes towards planet formation such

Effect of Number of Variants of Zirconium Hydride on Grain Growth of Zirconium
The microstructure characteristics of Zr-hydride in Zr are important concerns in metallurgy and nuclear engineering. In particular, it is known that the correlation between hydride and the grain boundary microstructure has a great influence on properties.
