Ověření přesnosti matematického modelu pro predikci fázových podílů a mechanických vlastností programu TTSteel při kalení ocelí

Abstract

The present Diploma Work concentrates on hardening of selected grades of fine steel under standard running conditions in hardening shops. It focuses on comparison between resultant values of hardened steels reached in hardening shop and computed using TTSteel software. The goal is to assess based on the actual results the usability of the software in hardening shops. The characteristic to compare were hardness and microstructure. The theoretical part of the present Diploma Work focuses on fundamentals of heat treatment and describes main physical factors that would influence characteristics of heat treated steels. A reference is made to the characteristics of various grades of steel by their classification and usage. The practical part of the present Diploma Work brings the evaluation of resulting values reached by actual hardening; those computed using the TTSteel software and their mutual comparison. The final assessment and conclusion come in the final chapter.
