Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    The method of accelerated cooling under excess pressure yields alloys of the system Al−Pb with lead content of up to 40%.

  2. 2.

    When the lead content is increased from 10 to 40%, maximum unit shortening in compression of unannealed Al−Pb alloys decreases from 75 to 50%, and maximum reduction in rolling decreases from 90 to 65%.

  3. 3.

    Alternating plastic deformation and annealing make it possible to obtain strip 0.08–0.1 mm thick of Al−Pb alloys in which the diameter of the lead inclusions does not exceed 2 μm.

  4. 4.

    Aluminum alloys containing up to 40% Pb may be recommended as material for journal bearing liners.
