Kinetics and temperature dependencies of the structure and phase composition changes in beryllium bronze under the artificial aging in stationary magnetic field have been studied. Influences of the magnetic field on microhardness, lattice parameter, size of the blocks of coregent scattering, dislocation density and relative microstrain of the matrix blocks were estimated as well as on the size and density of new phase precipitations. Effect of the bronze strengthening caused by the aging in magnetic field has been found which is connected with the formation and growth of new phase precipitations.
