Conclusions
-
1.
A relationship was found between phase transformations and chemical microheterogeneity of the solid solution in steels 1Kh15N5AM3 and 1Kh16N4AB.
-
2.
It was confirmed that δ ferrite can exist in equilibrium and nonequilibrium conditions in these steels.
-
3.
The amount of δ ferrite can be controlled by changing the holding time.
