Structurally defined glassy metal strips
First Claim
1. A strip of glassy metal having a thickness of from about 0.02 to about 0.14 mm, and being structurally defined in having substantially corresponding protrusions and indentations on opposite surfaces, said protrusions and indentations being defined by walls having a height and depth of from about 0.1 to about 20 times the thickness of the strip, with the provisos that(a) walls defining protrusions and indentations of height and depth respectively of less than the thickness of the strip are not steeper than about 88°
- , measured with respect to the base surface of the strip; and
(b) walls defining protrusions and indentations of height and depth greater than the thickness of the strip are not steeper than(i) about 65°
, measured with respect to the base surface of the strip, when arranged in direction transverse to the length of the strip,(ii) about 85°
, measured with respect to the base surface of the strip, when arranged in longitudinal direction of the strip, and(iii) between 65° and
85°
, measured with respect to the base surface of the strip, when arranged in direction between the transverse and the longitudinal.

Abstract
Structurally defined continuous metal strips are formed by forcing molten metal onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body. The surface of the chill body (chill surface) whereon casting of the strips takes place has a contoured surface, i.e. it is provided with structurally defined protruberances and/or indentations, which are faithfully replicated by the formed strip, the thickness of the strip being substantially uniform throughout, regardless of whether it replicates a level area of the chill surface or a raised or indented area.
