Abstract

A metallic glass part is provided. The metallic glass part includes an alloy core and a metallic glass shell surrounding the alloy core. The alloy core provides compressive force on the metallic glass shell at an interface between the alloy core and the metallic glass shell.

First claim

The invention claimed is:

1. A part comprising:
an alloy core; and
a metallic glass shell surrounding the alloy core;
the alloy core providing a compressive force on the metallic glass shell at an interface between the alloy core and the metallic glass shell, wherein the metallic glass shell and alloy core compromise the same alloy composition.

2. The part of claim 1 wherein the interface is a chemical bond between the alloy core and the metallic glass shell.
