Purpose: of this paper is to present numerical methods for calculation of CCT diagrams for engineering steels. Design/methodology/approach: The presented numerical methods for calculating the anisothermic diagrams of supercooled austenite are based on physical, statistical or artificial intelligence methods. In many cases input data are chemical composition and austenitising temperature. The results of calculations consist of temperature of the beginning and the end of particular transformation, the volume fraction of structural components and hardness of steel after heat treatment. Findings: Numerical methods are an alternative to experimental measurement in providing the material data required for heat treatment process simulation. Research limitations/implications: All presented methods for calculation of CCT diagrams for engineering steels are limited by ranges of mass concentrations of elements. Practical implications: All presented methods may be used in computer steel selection systems for machines parts manufactured from engineering steels subjected to heat treatment. Originality/value: The presented methods can be used for selecting steel with required structure after heat treatment. Keywords: Computational material science; Artificial intelligence methods; Neural networks; CCT diagrams
