“…During SST process at 630 • C, Fe atoms gradually diffused into the matrix, thus leading to the small Al 3 Fe phase dissolved and the morphology of large Al 3 Fe phase transformed into rod-shape ( Figure 4). Based on Gibbs-Thomson theory [17], the concentration on the boundary of the small phase is greater due to the larger curvature. Therefore, the solute atoms would diffuse from the side of small phase to the side of large phase.…”

Low-cost heat-resistant Al-Sc-Zr-Fe conductor wires were successfully manufactured by continuous rheo-extrusion process, and the mechanical and conductive properties of the materials were analyzed and compared after three different thermo-mechanical treatment methods. The coarse plate-shape Al3Fe phase transformed to small sized rod-like phase after solid solution treatment at 630 °C for 21 h. Direct aging treatment at 300 °C for 24 h led to the refinement and spheroidization of Al3Fe phase with a diameter of 200 nm. After the subsequent aging treatment at 300 °C for 24 h, the tensile strength and conductivity of the alloy wire significantly increased due to the homogeneous precipitation of the coherent spherical Al3(Sc, Zr) phase with an average size of 15 nm. The tensile strength, elongation, and conductivity of the alloy conductor wire after optimized thermo-mechanical treatment reached 165.7 MPa, 7.3%, and 60.26% International Annealed Copper Standard (IACS), respectively. The thermal resistance of the present alloy wire was superior to that of standard AT1 type alloy conductor according to IEC international standard.

“…Therefore, Al-Ni alloy has the advantages of high melting point, low density, good oxidation resistance and corrosion resistance. As another important alloy element, Sn has the properties of low surface tension, good electrical and thermal conductivity, excellent ductility and low melting point, etc., and it is usually added to metals and alloys [13][14][15] to improve the microstructure and mechanical properties of alloys [16][17][18]. In particular, adding an appropriate amount of Sn to Al-Ni alloy can reduce the melting temperature, which is very important for high-pressure solidification.…”

The microstructure, phase composition and mechanical properties of ternary Al-5.4Ni-2Sn (mass fraction) alloy solidified under different high pressures were researched. The results show that the phase composition of the alloy solidified at different pressures is Al, Al3Ni and β-Sn. The thermodynamic phase diagram of the ternary alloy Al-5.4Ni-2Sn was calculated under the equilibrium condition. The results demonstrate that the solidification process is as follows: L→Al3Ni→(α-Al + Al3Ni)eutectic→(α-Al + Al3Ni + β-Sn)eutectic. The hardness values of α-Al phase at ambient pressure, 2 GPa and 4 GPa are 1.5 GPa, 1.62 GPa and 1.99 GPa, respectively. This is an increase of 8% and 32.7%, respectively. The hardness of β-Sn phase decreases by about 31.2% at 4 GPa. When the deformation is 30%, the compressive strength at ambient pressure, 2 GPa and 4 GPa is 538.1 MPa, 1403.2 MPa and 1547.9 MPa, respectively. The compressive strength under high pressure increased by 160.85% and 187.7%, respectively.
