Stanovení prokalitelnosti oceli C45 pomocí U-křivek

Abstract

Bachelor thesis deals with the problem of heat treatment and determination of hardenability. Summary focuses on the theoretical basics nature of heat treatment. Average effect of test samples on hardenability was experimentally tested. Test bars of various diameters were subjected to metallographic analysis and the individual samples was recorded hardness. The aim is to verify the theoretical and experimentally obtained facts for round bars of steel C45.
