Analysis of the initial deformabiliti of austenitic stainless stells with a bend test
Austenitic stainless steel solidify under non-equilibrium conditions, and form two-phase microstructure of austenite and δ-ferrite. Workability of steels in hot are better in the primary crystallization of δ-ferrite. The influence of chemical composition on solid-state formation of delta ferrite pha...

| Summary: | Austenitic stainless steel solidify under non-equilibrium conditions, and form two-phase microstructure of austenite and δ-ferrite. Workability of steels in hot are better in the primary crystallization of δ-ferrite. The influence of chemical composition on solid-state formation of delta ferrite phase during hot deformation was investigated. The laboratory prepared austenitic stainless SS2343 steel with the Cr<sub>eq</sub>/Ni<sub>eq</sub> index – 1,62 were chosen for this research. The transformation of δ-ferrite during annealing in range 1 050 – 1 250 °C was analyzed. Hot bending test was selected for the evaluation of the initial plasticity of “as cast” SS2343 steel. Bending test of as cast steel plates with volume fraction 12,5 % of δ-ferrite have shown, that cracks do not form. |
