Effect of Nickel Additives and a Constant Magnetic Field on the Structure and Properties of Aged Copper–Beryllium Alloys

The results of an integrated experimental study of the effect of doping nickel additives (0.4 and 1.0 wt %) on the kinetic processes that occur during the artificial aging of copper–beryllium alloys in a constant magnetic field are described. A “negative” magnetoplastic effect, the magnitude of which reaches ∼35%, is discovered. The presence of nickel additives leads to a significant increase in the microhardness of the alloys and a change in their lattice parameters and fine structure; however, a change in the quantitative content of additives from 0.4 to 1.0 wt % ambiguously affects the measured quantities. © 2018, Pleiades Publishing, Ltd.
