Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    Cooling alloys A12 and A19 to negative temperatures greatly reduces internal residual stresses and consequently increases the stability of dimensions of precision parts.

  2. 2.

    The effectiveness of cooling to negative temperatures increases if combined with heating.

  3. 3.

    The effectiveness of cyclic treatment increases together with complexity of shape and with increase in the clearance dimensions of the parts.
