Conclusions
-
1.
C−C−T diagrams for alloy AK6 and a nomogram for determining the permissible cooling temperature and time were constructed.
-
2.
The stability of the supersaturated solid solution of alloy AK6 after DHT at temperatures above 420°C is the same as, and at temperatures below 420°C somewhat lower than, after standard treatment.
-
3.
Cooling below 105°C during quenching has no effect on the ultimate strength of alloy AK6.
