Abstract
Metallic glass powder is prepared by heating a solid metallic glass body to a temperature below its glass transition temperature for time sufficient to effect embrittlement, followed by comminution of the embrittled metallic glass body.
Claims4
Metallic glass powder having particle size of less than 4 mesh (U.S. Standard) comprising platelets having thickness of less than 0.1 millimeter, each platelet being of substantially uniform thickness throughout, and each platelet being defined by an irregularly shaped outline resultant from fracture of a substantially uniform thickness rapidly solidified embrittled amorphous material.
