Conclusions
-
1.
The crack propagation resistance, determined by Irwin's criterion K1C, increases with the nickel and manganese concentrations in precipitation-hardening austenitic steels.
-
2.
When austenitic steel is alloyed with chromium the variation of K1C with the concentration of the alloying element is characterized by a peak at 3.5% Cr.
-
3.
The use of data concerning the effect of alloying on the crack propagation resistance makes it posble to optimize the strength characteristics of precipitation-hardening austenitic steels more precisely.
