Abstract
Methods and systems for preparing metallic alloys comprising volatile materials such as phosphorus suitable for bulk metallic glasses are described. The methods variously involve carrying out alloying at temperatures and pressures that minimize or counteract sublimation of the volatile species.
Claims23
A method of preparing a metallic alloy, comprising:
- placing multiple constituents into a container;
- heating the multiple constituents in the container to initiate an alloying reaction among the multiple constituents in the presence of an inert atmosphere provided to counter sublimation of a first constituent which is a volatile species of the multiple constituents, the alloying reaction being initiated at a temperature below a melting temperature of the first constituent;
- forming a melt of the multiple constituents;
- and
- cooling the melt, thereby forming the metallic alloy.

A method of preparing a metallic alloy, comprising:
- placing multiple constituents into a container;
- evacuating and sealing the container;
- heating the multiple constituents in the container to initiate an alloying reaction among the multiple constituents, the container being in the presence of an external pressure sufficient to counteract a vapor pressure of volatile species inside the container, the alloying reaction being initiated at a temperature below a melting temperature of the volatile species;
- forming a melt of the multiple constituents;
- and
- cooling the melt, thereby forming the metallic alloy.
