    Notes: Conclusions 1. The use of ESR for beryllium bronze eliminates resegregation, reduces the oxygen content, refines inclusions, and improves the ductility. This makes it possible to increase the annual output and to use greater reductions (∼90%). 2. After quenching and aging or MTT of beryllium bronze BNT1.9Mg melted by ESR the bronze has a higher elastic limit and relaxation resistance under conditions of cyclic and static loading, high resistance to creep, high fatigue strength, high electrical conductivity, and higher fracture toughness as compared with standard VI bronze.

    Notes: Conclusions 1. On adding up to 0.4% Mg to beryllium bronze type Br BNT1.9 development of the advance precipitation or zone stage is accelerated during aging in the temperature range 150–340°C, and this is revealed in a reduction in activation energy for the process of supersaturated solid solution decomposition. 2. The structural state recorded in beryllium bronzes after low-temperature aging, corresponding to the initial stages of solid solution decomposition, is similar to that obtained in the initial stages of decomposition with short-term, high-temperature aging.
