Filaments of glassy metallic alloys prepared by chill block melt-spinning are consolidated under heat and pressure by uniaxial pressing to form discrete self-supporting glassy metallic alloy bodies of substantially uniform composition.

Warm consolidation of glassy metallic alloy filaments

Metallic ribbon having cutout patterns therein is provided in continuous helical form. The cutout patterns may be situated to intersect either or both of the ribbon edges or may be situated entirely within the ribbon. The helical ribbon with the cutout patterns may additionally have a nesting, or self-stacking, feature.

Patterned helical metallic ribbon for continuous edge winding

Filaments of glassy metallic alloys prepared by chill block melt-spinning are consolidated under heat and pressure by an extrusion process. Products obtainable by the process include discrete bodies of glassy metallic alloys of substantially uniform composition and articles having one or more layers of glassy metallic alloy clad onto one or more non-glassy metallic alloy substrates.

Method for producing compacts and cladding from glassy metallic alloy

Metallic ribbon having cutout patterns therein is fabricated in continuous helical form by directing a melt stream or jet onto a rapidly moving patterned substrate surface.

Method of making patterned helical metallic ribbon for continuous edge

Metallic ribbon is provided in continuous helical form. The ribbon may be nested and/or manufactured with a continuous pattern of predetermined geometry in the inner and/or the outer edge as well as in the interior of the ribbon.

Helical metallic ribbon for continuous edge winding applications

A bearing gas flow minimizes dynamic fluctuations in the molten alloy puddle from which metallic ribbon is formed during chill block melt-spinning. The bearing gas flow causes an improved quench rate and melt puddle stabilization which results in reduced upper ribbon surface texture and improved edge definition.

Method for melt puddle control and quench rate improvement in

Metallic ribbon is fabricated in continuous helical form by directing a melt stream or jet onto a rapidly moving substrate surface. The axis of the crucible along which the melt stream or jet is cast is defined by an inverted cone with apex at the point of crucible axis intersection with the substrate surface.

Method of making helical metallic ribbon for continuous edge winding

A bearing gas sleeve coaxial with the melt ejection crucible is provided in an apparatus for making glassy alloy ribbons to provide a confluent bearing gas flow which minimizes dynamic fluctuations in the molten alloy puddle from which metallic ribbon is formed during chill block melt-spinning. The bearing gas flow causes an improved quench rate and melt puddle stabilization which results in reduced upper ribbon surface texture and improved edge definition.
