Effect of High Pressure on the Compressibilities of Five Alloys

Abstract

The effect of high pressure has been measured on a series of alloys, including Fe plus 8 at. % Si, which has a (disordered) bcc structure, Fe₃Al and Fe₃Si, which have an ordered bcc structure, and FeAl and AgMg, which have the CsCl structure. The compressibilities of all the alloys except Fe₃Si decrease with increasing pressure and lie between those of the pure components. For Fe₃Si the compressibility increases slightly with increasing pressure and is less than that either of pure iron or pure silicon.
