Conclusions
-
1.
Differences in the rolling texture in steel 03Kh26N6T produced from different melts are not associated with the austenite content prior to rolling, but are governed primarily by the amount of solid inclusions of titanium carbonitrides.
-
2.
When austenite is present in steel prior to cold rolling, the metallographic texture is reduced after heating for SPD, and the more austenite present prior to rolling, the more equiaxial the shape of its particles.
-
3.
The level and anisotropy of the superplasticity characteristic of steel 03Kh26N6T sheets are determined mostly by the extent to which the austenite particles that form on heating for SPD are nonequiaxial.
