microlaminated microstructure - Opis:
- The aim of this work was to develop basic parameters of hot rolling and controlled cooling technology allowing to obtain the microlaminated (lamellar) microstructure in a lean-alloy structural steel containing 3÷5 wt % Al. Thermo-mechanical rolling tests of two experimental steels were carried out in a semi-industrial line comprising a one – stand reversing rolling mill. The final microstructure of the specimens subjected to rolling in the γ + α stability region characterised with the microlaminated morphology composed of lamellae of ferrite with thickness down to 1 μm or less and lamellae or grains of phases developed during transformation of the austenite. Determined parameters of the thermo-mechanical processing allowed to achieve very attractive mechanical properties of the experimental steels: tensile strength over 1.0 GPa and ductility level (total elongation) better than 15%.
