Abstract
Metallic glass powder is prepared by charging a solid metallic glass body with hydrogen to effect embrittlement, followed by comminution of the embrittled metallic glass body.
Claims11
A method for making metallic glass powder comprising:
- charging a solid metallic glass body with hydrogen at a temperature below its glass transition temperature for time sufficient to effect embrittlement, said body being a cathode in an electrolytic solution capable of generating hydrogen at said cathode;
- and comminuting the embrittled metallic glass body.
