Conclusions

  1. 1.

    Microalloying with phosphorus (0.02–0.10%) increases the tendency of beryllium bronze B2 to discontinuous decomposition. The maximum rate of discontinuous decomposition is reached with 0.05% P.

  2. 2.

    Discontinuous decomposition in quenched bronze B2, including the bronze microalloyed with phosphorus, occurs in a narrow range of aging temperatures (300–380°). The lower the quenching temperature and the greater the heterogeneity, the greater the degree of discontinuous decomposition during subsequent aging.

  3. 3.

    Microalloying with phosphorus and thermomechanical treatment under the conditions developed lower the electrical resistivity of beryllium bronze by 30–40% with retention of a high elastic limit (70–75 kg/mm2).
