M. Stańczyk, T. Figlus, The Silesian University of Technology, Faculty of Transport Katowice, Poland In the work the influence results of two different hardening coolant agents on the basic mechanical proprieties and microstructure of the round hot rolled bars were presented. The bars of 42CrMo4 steel were exposed to analysis, and for those bars in the hardening process, water and modern pro-ec...

The influence of thermomechanical deformation on the residual stresses caused by quenching in bar shaped specimens of heat treatable steel 42CrMo4 has been investigated using a mechanical method for detemining the distribution of residual stresses of the first kind. The results obtained show that the residual stress distribution after quenching is dected by the strengthening and softening of th...

Original scientific paper In this paper, influence of flame spraying and fusing on microstructure of substrates made from heat treated carbon steel C45, a heat treated low alloyed 42CrMo4 steel and stainless austenitic steel X6CrNiMo18-10-2, has been investigated. Flame spraying and fusing is a deposition technique commonly applied to nickel-base self-fluxing alloys (NiCrBSi alloys). Because of...

In this paper, the corrosion behaviour of 42CrMo4 low-alloy steel after normalizing, soft annealing, spheroidizing annealing and full is investigated. for quenching tempering, one widely used studied steels due to its good combination mechanical properties. Sometimes, it in annealed condition. Nevertheless, properties are poorly studied, especially The main objective work increase knowledge abo...
