“…For annealed materials, two peaks on the DSC curve were recognized. The first peak can be associated with Cu 3 Zr or Cu 5 Zr precipitation in the range of 471 -539 ∘ C. According to the study [26,28], the second peak (in the range of 563 -584 ∘ C) can be associated with recrystallization. After AScR, a double peak is seen on the DSC curve and a start of precipitation is shifted to the temperature of 434 ∘ C and recrystallization is a part of the precipitation peak.…”

This work deals with comparing the mechanical properties of OFHC copper and CuCrZr alloys processed by asymmetric ambient rolling (ASaR) and asymmetric cryorolling (AScR). The conditions for asymmetrical rolling were ensured by different diameters of the main rolls. The thickness of samples was reduced about 20% - 70% at ambient temperature and at a temperature of liquid nitrogen. Mechanical properties such as yield strength, tensile strength, reduction of area and microhardness were determined for all rolled samples. Rolling at cryogenic temperatures provide about 50-60MPa more tensile strength for Cu and 60-80 MPa for CuCrZr alloys when rolling at ambient temperature. After AScR of CuCrZr alloys, a start of precipitation was shifted at the temperature of 434∘C and recrystallization was a part of the precipitation peak. According to the results, plastic deformation through shear bands is the dominant mechanism in materials with lower stacking fault energy (CuCrZr) treated under cryogenic conditions.

“…The reported values of activation energy was 117.12 kJ/mol for the ECAPed (after 16 passes, equivalent strain per pass = 1.155) Cu-1Cr-0.1Zr alloys [50], which is much higher than the activation energy in the present study (64.5 kJ/mol for 4.5% Al and 66 kJ/mol for 2% Al).…”

“…The rods were then processed by ECAP at room temperature up to one pass using route B c . Full details of the ECAP processing can be found in [34,35]. This route was specially chosen for generating a fine equiaxed microstructure with a high volume fraction of highangle grain boundaries [31].…”

The precipitation of nano-sized Cr clusters was investigated in a commercial Cu-1Cr-0.1Zr (wt.%) alloy processed by equal-channel angular pressing and subsequent aging at 550 • C for 4 h using Small-Angle Neutron Scattering (SANS) measurements and High-Angle Annular Dark-Field-Scanning Transmission Electron Microscopy (HAADF-STEM). The size and volume fraction of the nano-sized Cr clusters were estimated using both techniques. The parameter values assessed by SANS (d ∼ 3.2 nm, Fv ∼ 1.1 %) agreed reasonably with those by HAADF-STEM (d ∼ 2.5 nm, Fv ∼ 2.3 %). In addition to the nano-sized Cr clusters, HAADF-STEM indicated the presence of rare cuboid and spheroid sub-micronic Cr particles measuring approximately 380-620 nm in mean size. Both techniques did not evidence the presence of intermetallic CuxZry phases within the aging conditions.
