Formula Derivation and Application for Carbon Content versus Heating Temperature in Austenitizing of Cast Iron
In this paper, a formula for the calculation of the carbon content during the austenitizing of cast iron was deduced, considering the effect of silicon content upon the heat-treatment parameter. According to this formula, the carbon content of the austenite at a certain austenization temperature for a cast iron with given components can be easily calculated, and the austenization temperature required to give the expected carbon content in the austenite can also be determined. Moreover, according to the relationship between the austenization temperature Tx and the associated carbon content Cax,, and considering the effect of the silicon content, a diagram showing Cax, Tx and the silicon content during the austenitizing of cast iron was prepared.
