Solidification and flow behaviour of mould fluxes

2002
Mould fluxes are synthetic slags added to the molten steel surface in the copper mould and provide lubrication by melting and infiltrating the gap between the solidified steel and mold. The use of mould lubricants in continuous casting of steel has been an important operational measure since the inception of continuous casting as early as the 1940's ...

Solidification behaviour in plasma are welding

Sadhana, 2001
Melting and solidification behaviour in the deep penetrution welding process is different from that in conventional welding process in deep penetration processes there is keyhole formation and the full thickness of the plate receives the are heat input unlike conventional processes in which the heat input is received only by the surface nodes.

Solidification behavior of PLLA/nHA nanocomposites

Composites Science and Technology, 2010
As part of a broader effort to establish processing-structure-property relationships in PLLA/nHA, which is currently under consideration for bioresorbable scaffolds for bone repair, hot stage optical microscopy and differential scanning calorimetry have been used to investigate the solidification behavior of a series of medical grade PLLA/nHA ...

The solidification behaviour of dilute aluminium–scandium alloys

Acta Materialia, 1998
Abstract The solidification behaviour of dilute Sc containing Al alloys has been investigated. In binary Al–Sc alloys, Sc additions greater than the eutectic composition (0.55 wt%) were found to produce a remarkable refinement in the grain size of aluminium castings, of two orders of magnitude, due to the formation of the primary Al3Sc intermetallic ...

Solidification behaviour of undercooled peritectic Fe81.68Co18.32 alloy

Journal of Alloys and Compounds, 2009
Abstract Rapid solidification of undercooled peritectic Fe 81.68 Co 18.32 alloy was investigated using fluxing method. With the increase of initial melt undercooling (Δ T ), different microstructures were observed. For low Δ T , a typical peritectic microstructure, if Δ T exceeded a critical value, 177 K, metastable phase was observed in the as ...

Solidification behaviour of squeeze cast aluminium composites

AIP Conference Proceedings, 2020
The effect of die temperature on the solidification behaviour of aluminium mixed ceramic cast samples are studied. The samples are prepared by squeeze casting method. The die temperatures are assigned in this work from 220 - 280°C and the preparation of aluminium in liquid state of temperature is 850°C, respectively.

Solidification behaviour of organic nonlinear optical crystals

Progress in Crystal Growth and Characterization, 1988
Abstract A representative rather than exhaustive review has been given on the solidification behaviour of organic nonlinear optical crystals. Many of the developments reported here represent quick experimental responses to the rapid theoretical advances made in the field of nonlinear optics. The article is divided into four parts.

Solidification behaviour of Fe–Gd–Mo alloys

Journal of Alloys and Compounds, 1999
Abstract Microstructures of the solidified Fe–Gd–Mo ternary alloys have been examined using optical and scanning electron microscopy. The nature and chemical composition of the different phases present have been determined by electron probe X-ray microanalysis and X-ray diffraction.

Solidification behaviour of binary sitosteryl esters mixtures

Food Research International, 2002
Phytosterol esters are known for their blood cholesterol lowering effect and have consequently been incorporated into vegetable oil table-spread products. In furtherance to gaining knowledge about these materials in a fat-blend environment, the current work describes the phase-diagram based thermal characteristics of a series of β-sitosterol alkyl ...

Solidification behaviour under intensive forced convection

Materials Science and Engineering: A, 2005
Abstract Solidification behaviour of AZ91D Mg-alloy and 357 Al-alloy under intensive forced convection in the rheo-die-casting process, was investigated experimentally to understand the effects of the intensity of forced convection and shearing time on the nucleation and growth behaviour.
