Selective crystallization of bulk amorphous alloy
First Claim
Patent Images
1. A method, comprising:
- crystallizing a portion of a bulk amorphous alloy part, the portion being less than the entire part; and
removing substantially all of the crystallized portion by machining a local portion of the part, the local portion including less than an entire surface of the part, thereby forming an at least partially amorphous part.

10. A method, comprising:
-
heating a portion of a part comprising a bulk amorphous alloy to a first temperature to form a transformed portion of the part comprising a crystalline phase, wherein the transformed portion is adjacent a non-transformed portion of the part and has a lower mechanical strength than the non-transformed portion; and removing substantially all of the transformed portion using a mechanical removal operation to form a cavity in a surface of the part. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
