Cr-V ledeburitic cold-work tool steels
Peter Jurči
Pregledni znanstveni članek
Oznake: P/M cold-work steel Vanadis 6;heat treatment;surface engineering;microstructure;hardness;three-point bending strength;fracture toughness;
Cold-work tool steels based on Cr-V alloying belong to the most important toolmaterials for large series manufacturing. To enable high production stability, the tools must withstand various types of degradation processes, concerning firstly plastic deformation and wear. Therefore, the materials shou ...

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 ...

Fracture characteristics of the Cr-V ledeburitic steel Vanadis 6
Peter Jurči, Borivoj Šuštaršič, Vojteh Leskovšek
Izvirni znanstveni članek
Oznake: ledeburitic Cr-V PM steel;heat treatment;sub-zero treatment;bending strength;fracture toughness;fracture surface;
The P/M Vanadis 6 is a very popular tool steel used for different cold work applications. The specimens for the three point bending tests and fracture toughness test were austenitized at two different temperatures, quenched with or without the sub-zero treatment and then double tempered. The bending ...

Changes to the fracture behaviour of the Cr-V ledeburitic steel vanadis 6 as a result of plasma nitriding
František Hnilica, Josef Čmakal, Peter Jurči
Strokovni članek
Oznake: ledeburitic steel;plasma nitriding;fracture toughness;crack propagation;
Three-point test specimens made from VANADIS 6 ledeburitic steel were heat treated using two basic regimes to produce different hardness values. The cross-sections of the specimens ranged between (10x10) mm and (1x10) mm - this range was chosen in order to evaluate the influence of the portion of ni ...

Microstructural evaluation of rapidly solidified Al-7Cr melt spun ribbons
Peter Jurči, Mária Dománková, Mária Hudáková, Borivoj Šuštaršič
Izvirni znanstveni članek
Oznake: rapid solidification;melt spinning;ribbons;microstructure;
The use of conventional bulk materials is limited by segregation phenomena, which are generated during the solidification and cannot be eliminated in the solid state. The introduction of rapid-solidification technology (RST) into material processing overcame some of the problem of unacceptable mater ...

Microstructural features of Cr-V ledeburitic saturated with nitrogen
Peter Jurči, František Hnilica, Jan Suchánek, Pavel Stolař
Izvirni znanstveni članek
Oznake: P/M cold-worked steel;plasma nitriding;twinned and dislocated martensite;phase constitution;
This paper reports on the microstructure, the hardness and microhardness, the nitrogen-concentration depth profiles and the phase constitution of plasma-nitrided P/M VANADIS 6 cold-worked steel. The initial microstructure ofthe steel consists of a matrix with twinned and dislocated martensite and pa ...
