Metal Science and Heat Treatment of Metals Aims and scope

Summary

  1. 1.

    A method has been developed for obtaining bicrystal specimens for stress-rupture testing.

  2. 2.

    It has been found that zinc and manganese segregate at the grain boundaries of solid solution of aluminum -copper-zinc and aluminum-copper-manganese.

  3. 3.

    It has been found that zinc lowers the high temperature strength of the grain boundaries in aluminum-copper alloys, while manganese increases it.
