    Investigation of “reverse solution” in beryllium bronze (1982)
    Springer
    Metal science and heat treatment 24 (1982), S. 818-822 
    Details
    ISSN: 1573-8973

    Notes: Conclusions 1. Short heating to 500°C of beryllium bronzes hardened and aged at 300–340°C and also aged after cold plastic deformation leads to softening as the result of reverse solution. The effects of reverse solution are caused by the dispersion of the structure and do not depend upon the nature of the precipitate phases. 2. Beryllium bronze acquires resistance to reverse solution if in aging the α-solid solution decomposition occurs according to the interrupted precipitation mechanism. 3. Treatment for reverse solution at 500°C with a hold of 10 sec may be used as a method of softening of beryllium bronzes in place of the traditional intermediate hardening.

    Structure and properties of beryllium bronze microalloyed with phosphorus (1975)
    Springer
    Metal science and heat treatment 17 (1975), S. 872-875

    ISSN: 1573-8973

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions 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. 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. 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).

    Notes: Conclusions It is possible to obtain steel-babbitt bimetals with metallic bonding of the layers in the presence of tin alone. This bond improves the structural strength of the layers and the operating characteristics of slip bearings.

    Structural transformation mechanisms during aging of copper-beryllium alloys (1983)
    Springer

    Notes: Conclusions 1. Isothermal aging of beryllium bronze BrB2 at 260–400°C is accompanied by structural transformations connected with decomposition of supersaturated α-solid solution. 2. Formation of γ′-phase nuclei (or regeneration of GP zones) and also their growth proceeds at the expense of cooperative-displacement processes characterized by low activation energy (19.7–26.3 J/mole) and significant relaxation time (τ⋟10−1−102 sec).

    Structure and properties of beryllium bronze microalloyed with magnesium (1970)
    Springer
    Metal science and heat treatment 12 (1970), S. 106-111 
    Details
    ISSN: 1573-8973
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions 1. The addition of a surface-active element (magnesium) increases the dispersity and uniformity of the structure, reducing the average grain size of the α-solid solution and the inclusions of excess plases in quenched beryllium bronzes. 2. Microalloying of beryllium bronzes B2 and BNT1.9 with magnesium substantially improves their strength characteristics (elastic limit, relaxation resistance, cyclic strength) as the result of suppression of the discontinuous decomposition mechanism and the uniform strengthening of both the bulk and grain boundary areas. The best strength characteristics of beryllium bronzes were attained with 0.1$ Mg. 3. The newly developed compositions, alloyed with Mg, are designated BNT1.9Mg and B2Mg. The optimal heat treatment for these alloys is quenching from 770°C and aging at 320°C for 6h. 4. Commercial trials of the new beryllium bronzes showed that elastic elements of these bronzes have better combinations of basic properties than those of the standard compositions.

    Influence of ion-plasma treatment on the properties of copper spring alloys (1985)
    Springer
    Metal science and heat treatment 27 (1985), S. 513-517 
    Details
    ISSN: 1573-8973
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions 1. Ion-plasma treatment of the surface before final hardening heat treatment is an effective method of increasing the strength properties of spring alloys. 2. The character of the surface treatment providing the greatest hardening effect depends upon the mechanism of hardening of the alloy. In dispersion-hardening beryllium bronze the greatest hardening is obtained in bombardment of the part surface with argon ions before final aging, and in alloys hardened by subrecrystallization annealing with application to the part surface of a thin layer of titanium by spraying in a nitrogen atmosphere with subsequent annealing in this atmosphere. 3. Ion-plasma treatment may be used in the production operation for hardening treatment of critical elastic elements.
