Effects of trace calcium and strontium on microstructure and properties of Cu-Cr alloys

Muzhi Ma et al.

Summary: Cu-Cr-Ca and Cu-Cr-Sr alloys fabricated by thermo-mechanical treatment showed improved mechanical and electrical properties compared to Cu-Cr alloy. The softening resistance of the alloys was significantly enhanced by the addition of Ca and Sr elements. The high strength of the alloys was mainly attributed to dislocation strengthening and precipitate strengthening.

Revealing trace Si effect on precipitation behavior and properties of Cu-Cr-Zr alloy: Experiments and first-principles calculations

J. P. Qu et al.

Summary: In this study, the effect of Si addition on precipitation behavior and properties of Cu-Cr-Zr-Si alloy was investigated through experiments and theoretical calculations. The results showed that the addition of Si accelerated the precipitation of Cr-rich phase and reduced the migration energy of Cr in Cu. In addition, the addition of Si also lowered the Cu/Cr interface energy and delayed the growth of Cr-rich phase.

Enhanced softening resistance and mechanical properties of Cu-Ni-Sn alloy with Al, Zn and Si micro-alloying

Chengjun Guo et al.

Summary: Microalloying with Al, Zn, and Si was investigated for its effects on the microstructure, physical properties, and softening resistance of Cu-Ni-Sn alloy. The results showed that the addition of Al, Zn, and Si effectively suppressed the segregation of the alloy, resulting in increased hardness and softening temperature. The presence of Al and Zn solute atoms and the formation of Ni31Si12 phase inhibited discontinuous precipitation formation and dislocation movement, leading to excellent mechanical properties and softening resistance in the alloy.

Summary: The study revealed the relationship between the rolling-aging sequence and the microstructure evolution, mechanical-electrical properties of a hot rolled-quenched Cu-0.67Cr-0.27Zr-0.12Ni-0.03Si-0.04Ti alloy. A good combination of strength and electrical conductivity was achieved in the alloy through a specific aging-rolling-aging process, with strength improvement mainly attributed to dislocation density strengthening.

Effect of Cr and Sn additions on microstructure, mechanical-electrical properties and softening resistance of Cu-Cr-Sn alloy

Jiazhi Li et al.

Summary: The addition of Sn in Cu-Cr-Sn alloys promotes the precipitation of Cr phase and inhibits the coarsening of Cr precipitates, resulting in improved strength. Precipitation strengthening is the dominant mechanism for increasing the yield strength. Additionally, the high softening temperature of the designed Cu-Cr-Sn alloys is attributed to the inhibitory effect of Sn on the coarsening of Cr precipitates and delayed recrystallization of deformed structure.

Huiya Yang et al.

Summary: A novel Cu-Co-Ti alloy with high strength, high conductivity, and excellent softening temperature was fabricated via solid solution, cold rolling, and aging treatment. The strengthening, conductive, and anti-softening mechanisms of the alloy were studied, revealing that solid solution scattering and precipitation strengthening were dominant mechanisms affecting electrical and mechanical properties, while the high softening temperature was mainly due to the restricted coarsening of precipitates by the diffusion rate of Co in the Cu matrix.

Precipitation of Al3Zr by two-step homogenization and its effect on the recrystallization and mechanical property in 2195 Al-Cu-Li alloys

Qibing Liu et al.

Summary: The two-step homogenization (TS) method significantly improves the recrystallization resistance, strength, and ductility of 2195 Al-Cu-Li alloys by promoting the nucleation of Al3Zr and refining the grain structure. The improvement in strength is mainly attributed to the Orowan mechanism and grain refinement induced by Al3Zr precipitates, while the enhanced ductility is achieved by the deflection and zigzagging of crack propagation in the deformed lamellar structure of TS alloys.

Zr-containing precipitate evolution and its effect on the mechanical properties of Cu-Cr-Zr alloys

Yibo Du et al.

Summary: The Zr-containing precipitates in the Cu alloy first form coherent Zr-rich atomic clusters on the {111} crystal plane of copper during aging, which then transform into Cu5Zr phase as aging time increases. The contribution of Zr-rich atomic clusters and Cu5Zr precipitates to the yield strength of the alloy is calculated by coherency strengthening and Orowan strengthening, respectively. The total yield strength is very close to the experimentally measured strength.
