Claims15
A method, comprising:
- forming a bulk metallic glass, of a plurality of materials forming an alloy, said alloy being a non Be containing alloy;
- and
- stabilizing one of a plurality of phases of said alloy relative to another of said phases.
A method, comprising:
- forming a bulk metallic glass, of a plurality of materials forming an alloy having said plurality of materials having Zr, Nb, Cu, Ni, and Al;
- and
- adjusting ratios between said plurality of materials to stabilize one phase of said alloy relative to another.
A method, comprising:
- forming a bulk metallic glass of the form Zr57+-60 /2Nb5−δCu15.4Ni12.6Al10+δ/2,
- where δ is nonzero.
A method comprising:
- forming a bulk metallic glass of the form Zr58.47Nb2.76Cu15.4Ni12.6All10.37
A bulk metallic glass of the form Zr58.47Nb2.76Cu15.4Ni12.6Al10.37.
A method comprising:
- determining information about competing formation phases of a bulk metallic glass;
- and
- changing a ratio between components of said bulk metallic glass to stabilize one of said formation phases relative to another of said formation phases.
