Effect of heat treatment on the microstructure and properties of Cr-V ledeburitic steel = Vpliv toplotne obdelave na mikrostrukturo in lastnosti ledeburitnega jekla Cr-VKrum, Stanislav ; Sobotová, Jana ; Jurči, PetrDuplex coating of high-alloyed tool steels is the newest and most promising technology that allows improvements to tools in terms of wear resistance and service time. However, the deposition of thin ... films onto the nitrided surface is associated with problems that are not yet solved. To clarify the problem of the adhesion and mechanical properties of the system substrate/coating it is necessary to prepare the substrate with well-defined microstructural parameters. The Vanadis 6 PM ledeburitic steel was chosen as a substrate for surface processing. It was austenitised, quenched and double tempered to a desired hardness of HRC = (57-58). Some specimens were also sub-zero treated in order to improve the transformation of austenite to martensite. The microstructure of the heat-processed steel was examined using optical microscopy and scanning electron microscopy. The resistance to nucleation of fracture was assessed with the three-point bending-strength test and the fracture surfaces were subjected to a fractographic analysis.Source: Materiali in tehnologije = Materials and technology. - ISSN 1580-2949 (Vol. 44, no. 3, 2010, Str. 157-161)Type of material - article, component part ; adult, seriousPublish date - 2010Language - englishCOBISS.SI-ID - 816298
