Conclusions

  1. 1.

    The Cu 23.7% Zn 4.55% Al alloy has good technological and special properties after quenching.

     
  2. 2.

    Prolonged aging of the alloy at 100° does not induce noticeable changes in the properties because of SME. With rising aging temperatures the initial and final temperatures of the reverse martensitic transformation drop, the initial deformation of the samples under constant stress decreases, and the deformation not removed during heating in the temperature range of the reverse martensitic transformation also increases.

     
  3. 3.

    The effect of aging on the properties of β brass exhibiting SME is due to decomposition of martensite, which is responsible for the increase in stability in the course of prolonged operation at temperatures above 100°.
