Effects of Zr and (Ni, Si) additions on properties and microstructure of Cu–Cr alloy

A physically-based constitutive model for high temperature deformation of Cu-0.36Cr-0.03Zr alloy

“…Recently many investigations on CueCreZr system alloys mainly focused on the improvement of physical and mechanical properties of the alloys, such as strength and conductivity [14,15], ductility [16], thermal stability [17,18], hot deformation performance [19] and fatigue performance [20]. Based on compression tests on a gleeble 3500 in a wide range of temperatures and strain rates, this paper would investigate hot deformation behavior of Cu-0.36Cr-0.03Zr alloy and establish the physical-based constitutive model to describe the work hardening, dynamic recovery and dynamic softening behavior.…”

Enhanced strength and electrical conductivity of Cu–Zr–B alloy by double deformation–aging process

“…As aforementioned, dislocations introduced by cold deformation can provide preferred nucleation sites for precipitates, hence cold deformation is usually performed in the thermomechanical treatments of precipitation-hardened alloys [2,13,14]. It is found in the present study that the secondary deformation and aging process are an important step in the thermomechanical process, which hinder discontinuous precipitation mode and promote continuous one.…”

“…Copper-based alloys have been widely used in electric, electronic, transportation and machinery manufacturing industries because of the excellent electrical, thermal conductivities and ease of fabrication [1][2][3][4][5]. High electrical conductivity and high mechanical strength are simultaneously required in these industries.…”

Microstructure and Mechanical Characterization of a Dissimilar Friction-Stir-Welded CuCrZr/CuNiCrSi Butt Joint

“…From Figures 5 and 6, it is seen that the coarse particles in CuCrZr-NZ are primarily consisted of Cr element while Cr and Si element mainly concentrate on coarse particles in CuNiCrSi-NZ. Actually, these coarse particles are solute-rich particles which are formed during the solidification of the alloy due to the limited solubility of Cr and Si elements in Cu matrix [23]. Obviously, these coarse particles even cannot be solved during the process of FSW.…”
