RT Journal Article SR Electronic A1 Učeň, Michal A1 Filípek, Josef T1 The quantitative determination of products of isothermal desintegration of austenite JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 54 IS 1 SP 127 OP 134 DO 10.11118/actaun200654010127 UL https://acta.mendelu.cz/artkey/acu-200601-0012.php AB With the help of a constitution diagram Fe - Fe<sub>3</sub>C, a diagram TTT and vertical structural diagram of the authors' own construction it is determined that the relative amount of products in steel occurs in any temperature of isothermal disintegration of austenite. Making use of camouflage it is enabled to set bouth structural and phasic composition of alloy at the same time. In case of use of appropriate animating software (e.c. Macromedia Flash) it is possible to practise this quantification on steel of any chemical composition.
