Experimental studies of the aging of BrB-2 beryllium bronze in a constant magnetic field (PMF)
show a noticeable “negative” magnetoplastic effect (MPE), which consists in reducing the
ductility of the alloy and increasing the microhardness to 30% [1]. In some cases, the using a
accompanied by the formation of structural formations — coherent scattering blocks — with a
size of less than 100 nm [2], which we have identified as the nano-magnetoplastic effect
(NMPE). It is of interest to search for optimal aging regimes that lead to the greatest effects of
MPE and NMPE, and to establish the physical mechanisms of these effects
