Melt Generation and Extraction in Mantle Diapirs
1989The oceanic lithosphere, its physical, penological and geochemical nature, are largely a function of the magmatic processes which take place at oceanic spreading centers. An understanding of the processes of mantle melting and melt extraction is therefore central to models for the development of oceanic lithosphere.

Fabrication and Characterization of Slag Fiber by Melt Extraction
Materials Science Forum, 2007The influence of wheel speed and melt temperature on the surface characteristics of slag fibers were examined in mineral fibers synthesized from the steel-making slag, using a modified melt extraction method, i.e. melt spinning. The synthesized fibers were characterized by optical microscope and scanning electron microscopy. It was found that the wheel

Fundamentals of fibre formation during melt extraction
Materials Science and Engineering: A, 1991Abstract Investigations on fibre formation at melt extraction of a eutectic AlCu alloy and a heat resistant steel (type 304) reveal that the process can be described by a simple solidification model for intermediate cooling. In this case it is necessary to consider a meniscus being formed at the extraction edge of the disc.

Melt Extract Fibre Reinforced Sprayed Concrete
1985The performance of melt extract and wire fibre reinforced sprayed concretes produced at three field trials in the UK is reported. An emphasis was placed on measuring properties relevant to the applications of the material and in particular the effects of in situ fibre content and fibre type.

The wavelengths and directions of dimensional variations in metal ribbons quenched by Newtonian cooling from the melt are estimated for the melt-spinning and the melt-extraction processes. The main sources of dimensional variation are the vibration and distortion of the melt puddle from which the ribbon is solidified and the variation of the Newtonian ...

Abstract Melt viscosity affects virtually all aspects of igneous petrogenesis. Although addition of H2O is known to lower melt viscosities, addition of fluorine is controversial and may raise them. Because these two volatiles most commonly reach their highest concentrations in granitic rocks, the viscosities of peralkaline, strongly peraluminous, and

Physics of melt extraction: theory, implications and applications
Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1993Abstract This paper presents a general overview of flow in deformable porous media with emphasis on melt extraction processes beneath mid-ocean ridges. Using a series of simple model problems, we show that the equations governing magma migration have two fundamentally different modes of behaviour.
