Název v původním jazyce

Models of mean flow stress and structure evolution of iron aluminides in hot forming.

Popis výsledku v původním jazyce

Four iron aluminides (type Fe3Al) were tested with following additives: with TiB2, with Ti, with B, with Ti and B. Flat specimens with graded in size thickness were hot rolled. Deformation resistance was calculated, by method based on non-linear regression by means of the statistical software Unistat 5.5, from the roll force values that were measured in the laboratory rolling mill Tandem. Mathematical models of mean flow stress of selected iron aluminides depending on temperature and strain were developed. Postdynamic structure-forming processes of the tested aluminides were investigated by metallography after hot rolling in the laboratory mill stand K350. Three forming temperatures and three modes of cooling were used, and then the structures of eachiron aluminides were compared. Differences in deformation behavior and formability of the materials, which creep resistance at high temperatures is good, were described.
