Production of TiNi fibers by melt extraction
Powder Metallurgy and Metal Ceramics, 2008The paper examines the production of TiNi fibers by pendent-drop melt extraction in vacuum. The mean effective diameter of the continuous fibers produced is 37 µm. Resistometrical investigation establishes that martensitic transformations in the fibers start at Ms = 17 °C.

Underplating and Partial Melting: Implications for Melt Generation and Extraction
Science, 1989The quantitative assessment of underplating and concomitant partial melting of continental crust requires the use of geologically reasonable melt fraction distributions as a function of temperature. Conductive modeling indicates that simple underplating of metapelite by basalt can yield magma bodies with melt fractions above the rheological limit of ...

Fine fibres by melt extraction
Materials Science and Engineering: A, 1994Abstract Methods for manufacturing fine fibres of metals and ceramics below 20 μm diameter are described. Some analysis of the fabrication process is given as well as a description of properties of the fibres. A brief account is also given of selected applications of the materials.

IEEE Transactions on Magnetics, 1980
Crystallographically isotropic fibers of ferromagnetic τ-phase in the Mn-Al and Mn-Al-C alloy systems have been prepared by rapid quenching from the liquid state by melt extraction and subsequent heat treatment. The permanent magnet parameters for the fibers are greatly improved as compared to the values previously reported for isotropic alloys.

Melt-extracted oxide ceramic fibres — the fundamentals
Journal of Materials Science, 1996A melt-extraction technique, using a sharpened molybdenum wheel, has been used to produce fine oxide ceramic fibres. Wetting of the molybdenum wheel by molten ceramic is a key parameter in the melt-extraction process. Two types of fibre are generally obtained, depending on the extraction speed.

Amorphous CaO · Al2O3 fibers by melt extraction
Materials Science and Engineering: A, 1996Abstract A novel melt extraction technique has been used to produce fine calcium aluminate (CaO · Al 2 O 3 ) fibers with wheel velocities of 1.5–65 m s −1 . The geometry of the fibers depends on the wheel velocity; at speeds −1 uniform diameter fibers were obtained, whereas at higher velocities Rayleigh waves formed on the fibers owing to ...

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.

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.

Abstract The volume change associated with dehydration melting has been investigated experimentally in muscovite and biotite-bearing assemblages because it is a possible driving force for melt segregation during orogenesis. Experiments have been performed on cores of a muscovite+biotite-bearing pelite and on a biotite+plagioclase+quartz gneiss.

Abstract In the southern Tibetan Plateau, leucogranites are dominantly distributed in the Himalayan orogenic belt with minor occurrences in the southern Lhasa subterrane. In this paper, we report the first Miocene Anglonggangri leucogranites in the northern Lhasa subterrane.
