The influence of magnetic field on phase nucleation in Cu–Be alloy

We discuss the results of small-angle polarized neutron scattering on the diamagnetic Cu-Be alloy on annealing in the temperature range 300 K < T < 650 K from the quenched condition. The characteristic scale of phase nucleation depending on temperature and time was determined. The correlation in change of the integral cross-section of scattering neutrons on annealing with modulation ('on' or 'off') of a constant magnetic field in the range 0 Oe < H < 5700 Oe was found. These experimental results may be interpreted as the magnetic field influence on the kinetics of nucleation during artificial aging of Cu-Be alloy.
