Deformation-assisted decomposition of unstable Fe50Cu50 solid solution during low-energy ball milling

Distinct magnetic states of metastable fcc structured Fe and Fe–Cu alloys studied by ab initio calculations

“…by pulsed-laser deposition, one ML of Fe and one ML of Cu were alternately grown onto a Cu(1 0 0) substrate, and the obtained Fe/Cu layered structure was characterized to be in a FM state [39], which is in agreement with the present calculations. Another example is the experimental observation reported by Xu et al that an fcc structured Fe 50 Cu 50 solid solution was obtained by means of ball milling and its lattice constant was measured to be 3.64Å [40], which was also quite close to the value of 3.63Å predicted for L1 0 (fcc) by the present calculations.…”

“…Besides, the immiscibility between Fe and Cu could also be favored to expand the atomic volume. In short, the above calculation results suggest that it is possible to stabilize the predicted HSFM state of fcc Fe in the non-equilibrium Fe-Cu intermetallic compounds, and there have indeed been some experimental studies reporting the formation of such non-equilibrium alloys in the Fe-Cu system [39,40,42,43].…”

The γ-Fe formation in epitaxial Cu(001)/Fe(001) thin films by the solid-state synthesis: Structural and magnetic features

“…As is known, coherent [20][21][22][23][24]. Similar to many Fe-based alloys, the g-FeCu phase exhibits the invar effect [22].…”

Reverse martensitic transformation in alumina–15vol% zirconia nanostructured powder synthesized by high energy ball milling

“…On the other hand, the rate of stabilization is controlled by movement of cations which is a million fold smaller than that of the oxygen ions. HEBM provides positive thermodynamic driving force for monoclinic to tetragonal transformation occurrence [10] because HEBM is known to induce formation of nonequilibrium phases [20][21][22][23][24][25].…”
