Strength of Materials Aims and scope

Conclusions

  1. 1.

    In heat-resistant nickel alloys in the range of service temperatures, depending on their level, four types of tensile diagrams are used: with linear hardening, with exponential hardening, pure plastic, and with softening.

  2. 2.

    The presence in the load of a high-frequency cyclic component reduces on the whole the characteristics of short-time strength, causing corresponding displacement of tensile diagrams.

  3. 3.

    In the high-temperature region the effect of displacement of tensile diagrams is possible towards hardening, caused by the action of small cyclic loads with retention of plasticity level.
