    HOT DUCTILITY CHANGES OF MICROALLOYED STEEL WITH Mo ADDITION

  • Original language description

    The work presents results of plasticity response and strength levels of two micro-alloyed steels having different Ti, N and Mo contents. In temperature intervals of 600/650°C-750°C, 750°C-1000/1200°C and 1200°C-1350°C troughs of hot ductility expressed by reduction of areas were detected. Material with higher Mo content generally showed higher parameters of hot ductility. Reasons of the plasticity differences are expressed using chemical composition and possible bonds, using evaluation of mechanical properties such as yield strength and/or strength and by use of microstructure analysis results. In lower temperature interval, for the lower plasticity higher portion of formed allotriomorphic ferrite and bainite was typical, while the higher reduction ofarea was connected with higher volume fraction of acicular ferrite. The higher temperature intervals were related to higher volume fraction of precipitated particles on the austenite grain boundaries. In total plasticity response of given
