Conclusions
-
1.
Lowering the testing temperature from +20° to −60° reduces the durability of the steels investigated (to 15,000 cycles before failure).
-
2.
The relative change in the durability N−60°/N+20° depends on the energy of impact.
-
3.
With lowering of the testing temperature the durability changes most in the second stage — the period of operation of the sample (or machine part) with a crack.
-
4.
We determined the basic relationships in the effect of low temperature on the durability of samples subjected to impact loading, which are characteristic for structural carbon and alloy steels heat treated to relatively high hardness (HRC≥35).
