This article presents a method for analyzing heat treatment processes of steel parts, with the prediction of mechanical properties and microstructure, using models implemented in the "PoligonSoft" computational simulation system. Using the example of the automated implementation of quenching and tempering technology development in preparation for the production of a new type of product, the methodology for adjusting the modeling tool to the conditions of the available thermal equipment is demonstrated, and the general process of the computational study is described.

The article describes the updated model of exothermic material behavior implemented in the «PoligonSoft» 2024.0 software. Examples of numerical analysis of the solidification of parts manufactured using exothermic sleeves are presented, which demonstrate high reliability of the calculation results.

This article investigates the simulation of porosity and shrinkage defects in 14X17N2L steel castings using the simulation systems PoligonSoft and ProCAST. It compares standard models and the new porosity model implemented in PoligonSoft with actual castings. The article emphasizes the importance of improving algorithms to achieve more accurate predictions, recommending validating the models under controlled laboratory conditions to assess their applicability in real production.

A finite-element model of the piping and shrinkage macro porosity formation taking into account the capillarity and dendrites skeleton influence on feeding of the mushy zone were designed. The simulation results depend on melt physical properties - compression modulus and critical pressure at which creation of the interfacial area like internal shrinkage cavity or macro porosity becomes energy-possible. A software module for PoligonSoft CAE system has been developed. The results simulated in the module are in a good agreement with experimental data.
