Abstract
Abstract Strips of amorphous metal containing embedded particulate matter and method for making it. Strips of amorphous metal containing embedded particles of abrasive material are useful for working the surfaces of solid articles by abrasion for forming or surface improvement. The method of making such strips involves forcing molten metal of a glass-forming alloy containing admixed particulate matter 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.
