Thermodynymic Analysis of Cast Irons Solidification With Various Types of Graphite
Original language description
The contribution summarises the results of oxygen activity determinations, which were measured and registered continuously in castings from cast irons with various types of graphite. The results were used to find the relationship between two variables: natural logarithm of oxygen activities and reverse value of thermodynamic temperature 1 /T. Obtained regression lines were used to calculate oxygen activity at different temperatures, to calculate Gibbs free energy ?G at the different temperatures and tocalculate the single ?G value for significant temperature of the graphite solidification. The results were processed by a statistical analysis of data files for the different types of cast irons with flake, vermicular and spheroidal graphite. Each material has its proper typical oxygen activities range and individual temperature function of Gibbs free energy for analysing and governing casting quality.
