In this study, composite samples were produced by supplementing the CuNiSi powder mixture with Ti particles at different weight ratios using the powder metallurgy (PM) method. The prepared CuNiSi and Ti powder mixtures were turned into pellets by cold pressing under 500 MPa pressure. The pelletized samples were subjected to sintering in an atmosphere-controlled oven at 900 ℃ for 2 hours. Scanning electron microscopy (SEM-EDS), SEM-Mapping and corrosion experiments were performed to determine the microstructures of the produced samples. From the microstructure results, it was determined that Ti particles were distributed homogeneously within the structure. As the amount of Ti increased, the resistance of the composite to corrosion increased. In addition to that, as the amount of Ti increased, the resistance of the composite to corrosion decreased.

“…Liu et al [6] discovered that the incorporation of Cr, Zr, Ti, and Mg into the Cu-Ni-Si alloy leads to grain refinement and the formation of a twinning structure. Li et al [7] showed that the addition of Mg in the Cu-Cr-Zr alloy, through a two-step deep cold rolling and aging process, effectively improves both the electrical and mechanical properties of the alloy. Huang et al [8] discovered that the incorporation of Fe into the Cu-Ti alloy results in increased dislocation density, tensile strength, and quantity of deformation bands after cold rolling.…”

In order to design Cu-Sn alloys with excellent overall performance, the structural stability, mechanical properties, and electronic structure of X-doped Cu-Sn alloys were systematically calculated using first-principles calculations. The calculation results of the cohesive energy indicate that the Cu-Sn-X structures formed by X atoms (X = Ag, Ca, Cd, Mg, Ni, Zr) doping into Cu-Sn can stably exist. The Cu-Sn-Ni structure is the most stable, with a cohesive energy value of −3.84 eV. Doping of X atoms leads to a decrease in the bulk modulus, Possion’s ratio and B/G ratio. However, doping Ag and Ni atoms can improve the shear modulus, Young’s modulus, and strain energy of the dislocation. The doping of Ni has the highest enhancement on shear modulus, Young’s modulus, and strain energy of the dislocation, with respective values as follows: 63.085 GPa, 163.593 GPa, and 1.689 W/J·m−1. The analysis of electronic structure results shows that the covalent bond between Cu and X is the reason for the performance differences in Cu-Sn-X structures.

A new strategy has been developed to combine the nanotwins and dual‐scale particles into copper matrix composites and the comprehensive properties of Cu‐1Cr‐0.3Zr‐1ZrB2 exhibit excellently with the addition of intermediate aging and cryorolling. The effects of different deformation processes on the evolution of microstructure, room‐temperature and elevated‐temperature mechanical properties are investigated. The result demonstrates that the number of nano‐scale Cr precipitates increases obviously after intermediate aging. The nano‐sized Cr precipitates impede the movement of grain boundaries and dislocations, resulting in the refinement of deformation bands and the dislocation tangle. The combined effect of intermediate aging and cryorolling also improves the formation of nanotwins, which plays an important role in enhancing the tensile strength of composites. The tensile strength, elongation and conductivities of the composites subjected to two‐step cryorolling reaches 653 MPa, 8.02% and 79.51% IACS, respectively, showing an optimum comprehensive property. In addition, the stable nanotwins and the uniform distribution of dual‐scale particles inhibit recrystallization process at elevated temperature, contributing to improving the mechanical behavior at elevated temperature and heat‐resistant performance of composites.This article is protected by copyright.
