Cu-rich Precipitates Structural Forms During Decomposition of Alloys in Fe-Cu System
Structural forms of copper during decomposition of supersaturated solid solutions in the Fe-Cu system are analyzed in thermodynamic terms. First-principles methods are used to calculate free energies of BCC, 9R and FCC phases of copper at themperature 0 K. The possibility that a spinodal reaction, w...

| 总结: | Structural forms of copper during decomposition of supersaturated solid solutions in the Fe-Cu system are analyzed in thermodynamic terms. First-principles methods are used to calculate free energies of BCC, 9R and FCC phases of copper at themperature 0 K. The possibility that a spinodal reaction, which is followed by formation of a copper-rich BCC phase, takes place at initial stages of decomposition in the Fe-Cu system is substantiated. |
