Conclusions
-
1.
The mechanical properties of the investigated steels at normal and cryogenic temperatures improve when their aluminum content increases to 10%. Further alloying with aluminum causes some impairement of the plastic and ductile properties; this is connected with the formation of α-phase in the structure of the steels.
-
2.
Magnetic permeability is practically independent of the temperature in the range 293–4°K because of the complex magnetic transformations occurring during the freezing of steels.
-
3.
When steels are deformed with ε=40%, their texture is transformed, and this is accompanied by the displacement of the principal orientation of the texture from {110}<001> to {110}<112>. Such transformation leads to an anomalous decrease of magnetic permeability and electric resistivity of steels.
