The quality of twin roll thin strip is greatly effected by the columnar zone proportion in solidification structure of thin strip.

The heat regeneration of cylindrical V/AC catalyst for adsorbing SO2 and NH3 regeneration were studied by an atmospheric fixed-bed reactor.

Steel Billets without Columnar Grain in Continuous Casting-Semisolid Continuous Casting;

Directional recrystallization can be used to produce single crystals or columnar grain structure,which can show enhanced creep properties,improved low-cycle fatigue resistance and/or improve crack-stopping behavior.

Cu-Al-Ni wires with columnar grain structure fab- ricated by heated mold continuous casting process were con- ducted bending fatigue and tensile fatigue tests to study the behavior of grain boundaries in fatigue process.

Using appropriate process parameters, the Cu-Al-Ni shape memory alloy with good surface quality and unidirectional dendritic crystal was prepared by the self-made ohno continuous casting equipment.

Discotic liquid crystals self-assemble to highly ordered hexagonal columnar mesophase (Colho) and exhibit anisotropic high charge carrier mobility, and can be used as organic opto-electronic materials.

The results showed that these compounds exhibit high clearing points, stable columnar mesophases and wide mesophase ranges.

Distribution of the growth orientation of Ni-Ti alloy columnar crystal;

The results showed that pure copper plates of 25mm in width and 5mm in thickness with luminant surface and columnar crystals can be continuously and stably fabricated under the conditions of melting temperature 1160℃,drawing speed .

But for the copper formed of more thin wire, there are all columnar crystal a.

Compact processing of containing CuAlNi alloy pipes with continuous columnar crystals;

The results showed that the proper amount of additions of Na2O-MgO can obviously promote the formationβ-Al2O3columnar crystals,raise its aspect ratio,and increase the flexural strength and fracture toughness.

The results show that when nucleation temperature is lower than the temperature of endothermic peak of DTA curve, the columnar crystals grow in unidirectional direction from border to inner of the sample.
