Conclusions
-
1.
For 08Kh15N5D2T steel sharply expressed structural heredity is characteristic.
-
2.
In the steel with an increased titanium content an increase in the heating rate leads to a drop in the temperature of the start of recrystallization and an increase in the degree of grain refinement.
-
3.
The impact strength of the coarse-grained steel in the embrittled condition may be significantly increased by increasing the quantity of residual austenite, For the finegrained steel an increase in the quantity of residual austenite leads to a drop in the ductile-brittle transition temperature at normal and low temperatures.
