The Ageing of Beryllium Bronze in the Pulse Magnetic Field

Abstract:

Kinetics of changes of microstructure of beryllium bronze BrB-2 in d decomposition process of supersaturated solid solution in the pulse magnetic field with 0 – 7 Hz frequency with pulse intensity amplitude 318.4 кA/m (4 kOe) and magnetic field constant component 238.8 кA/m (3 kOe) under the temperature 350 °С and ageing duration 1 hour was investigated by microhardness measurements and X-ray diffraction. Frequency dependences of microhardness, lattice parameter, beryllium concentration in a residual matrix, size of coherent scattering blocks, dislocations density and the value of relative microdeformation of the matrix blocks under ageing in the pulse magnetic field and without it have been investigated. Experiment results show that the pulse magnetic field essentially influences the parameters of the fine structure and also physical and mechanical properties of bronze.
