Evaluation of the microstructural changes in Cr-V ledeburitic tool steels depending on the austenitization temperature
Pavel Bílek, Jana Sobotová, Peter Jurči
Strokovni članek
Oznake: Cr-V ledeburitic steels;Vanadis 6;MC carbides;M7C3;carbides;temperature of austenitization;
Samples of Vanadis 6 PM Cr-V ledeburitic steel were austenitized at temperatures in the range 1000-1200 °C and oil-quenched. The structural changes were investigated by scanning electron microscope and evaluated using NIS Elements software. The obtained results indicated that the M7C3-carbides under ...

Effect of heat treatment on the microstructure and properties of Cr-V ledeburitic steel
Stanislav Krum, Jana Sobotová, Petr Jurči
Strokovni članek
Oznake: sub-zero treatment;hardness;ledeburitic tool steel;
Duplex 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 p ...

Diagnostics of the microstructural changes in sub-zero-processed Vanadis 6 P/M ledeburitic tool steel
Jana Sobotová, Peter Jurči, Jan Adámek, Petra Salabová, Otakar Prikner, Borivoj Šuštaršič, Darja Jenko
Izvirni znanstveni članek
Oznake: P/M cold-work steel;heat treatment;sub-zero treatment;precipitates;
Specimens made from P/M Vanadis 6 cold-work steel were austenitized, quenched and tempered for various combinations of the parameters. The selected sets of samples, also in the sub-zero range, were treated at a temperature of -196 °C after quenching. The microstructure was investigated as a function ...
