“…The dislocation entanglement tended to decrease slightly with aging. Figure 4b,d suggests that the nanoscaled Cr-rich precipitate phase [11,12] distributes homogeneously in the matrix and the distribution density is basically the same. The fine particles with coffee-bean contrasts [14,15] are ~5 nm after annealing for 60 min.…”

The softening behavior of a cold-drawn Cu–Cr–In alloy was investigated during annealing between 450 °C and 700 °C. The properties and microstructure evolution of the alloy were characterized using a microhardness tester, electron back-scatter diffraction, and transmission electron microscopy. Elemental In addition was found to hinder the dislocation movement and delay the recovery and recrystallization of the Cu–Cr–In alloy. The experimental data were analyzed using the Johnson–Mehlv–Avramiv–Kolmogorov model. The activation energy of recrystallization of the 60% cold-drawn Cu0.54Cr0.17In alloy was 188.29 ± 18.44 kJ/mol, and the recrystallization mechanism of the alloy was attributed mainly to Cu self-diffusion.

“…In our previous work [11,12], a Cu-Cr-In alloy type was designed, and elemental In addition to the Cu-Cr alloy was found to yield a strong solid-solution strengthening effect. The alloy exhibits a high strength and good conductivity with facile preparation and production.…”

“…Quintic (power of 5) and hexic (power of 6) polynomial functions were fitted for steel [26] and copper alloys [27,28] . In previous work it was shown that only a 7-power heptic polynomial function could fit the curves well for Cu-Cr-In alloys [29] .…”

“…CALPHAD (Calculations of PHAse Diagram) approach definitely helps explain phase evolution and so on so forth [26]. In our previous work, a type of Cu-Cr-In alloy has been designed, which has good hot working formability and excellent comprehensive performance with high strength and high conductivity [27,28], but little research has been carried out for its solidification behavior. Therefore, in the present work, the influence of element In on the solidification behavior of Cu-Cr alloys are investigated using experimental and thermodynamic methods.…”

Solidification microstructure of Cu-Cr and Cu-Cr-In alloys has been characterized using scanning electron microscopy in the present work. Thermodynamic database has been established for the Cu-Cr binary system and Cu-Cr-In ternary system. Solidification behaviors of the two alloys have been simulated using the thermodynamic parameters based on Scheil model. The results show that the primary Cr phases with long and thin dendrites can be observed between Cu matrix grains for the Cu-Cr alloy, and the 'flower-like' coarsen dendrites primary Cr phases of the Cu-Cr-In alloy exist in the triangular grain boundary areas. The weight percent of indium element in the liquid phase of the Cu-Cr-In alloy during solidification continuously increases up. This will enlarge the solidification temperature range from 6°C to 214°C resulting in longer time for the dendrite growth and the alloying element indium with low melting point tends to segregate to the grain boundary region.
