Deformation resistance and structure-forming processes of iron aluminides in hot rolling.
Result description
We have developed simple mathematical models of mean equivalent stress dependence on temperature and strain for selected iron aluminides. Four similar melts with 16.5?19.2 wt.% of Al, 4 wt.% of Cr and with various contents of Ti and B were studied and compared. Flat specimens graded by thickness were hot rolled. Deformation resistance was calculated from the roll force values obtained using a laboratory mill Tandem. Postdynamic structure-forming processes of the tested aluminides, as well as their cracking susceptibility, were investigated by metallography. The differences in the deformation behavior and formability of the tested aluminides were described.

Czech description
Vyvinuli jsme jednoduché matematické modely závislosti středního ekvivalentního napětí na teplotě a deformaci pro vybrané aluminidy železa. Byly studovány a porovnávány čtyři podobné tavby s 16.5?19.2 hm.% of Al, 4 hm.% of Cr a různými obsahy Ti a B. Ploché vzorky srovnané posdle tloušťky byly tvářeny za tepla. Byl vypočítán deformační odpor z hodnot válcovací síly získané s použitím laboratorníhio zařízení Tandem. Postdynamické struturotvorné procesy zkoušených aluminidů jakož i jejich náchylnost k praskání byly vyšetřována metalograficky. Byly popsány rozdíly v deformačním chování a tvařitelnosti zkoušených aluminidů.
