Effect of Cerium and Boron on Microstructures and Properties of Cu-Ni-Si Alloy
The effects of trace boron and cerium addition on microstructures and properties of high-strength and high-conductivity Cu-Ni-Si alloys were studied. The results showed that the recrystallization starting temperature of Cu-Ni-Si alloy was greatly raised by adding trace Ce and B, which resulted in that the recrystallization of alloy did not happen until the aging strengthening peak was reached. Thus, the good strengthening effect contributed by both precipitation and cold working was obtained, and not only the peak strength was obviously increased but also the strength peak and conductivity peak appeared at the same aging temperature. The trace addition of Ce and B makes the alloys achieve an excellent combination of high strength and high conductivity.
