Resumo

The paper presents theoretical aspects and basic algorithms of the general metallurgical software tool (the static library MetaCool) developed for prediction of mechanical properties of steel after quenching and tempering. This model works independently of the concrete heat treatment technology and predicts final mechanical properties (hardness, ultimate tensile strength and yield stress) of steels cooled from austenitic state. The CCT-diagrams of steels are predicted from chemistry and conditions of austenitizing with taking into account the effects of transformation of deformed austenite. The MetaCool library can be linked to various off-line process simulation software or process monitoring systems created to design or control heat treatment or accelerated cooling technologies of concrete steel products. Examples of such technological software tools are presented together with some practical experience with the process simulation of heat treatment of tubes, bars and special profiles (QTSteel software).
