Prostorske predstave ljubljanskih učencev razredne stopnje o Ljubljani
Petra Šuštaršič, Irena Hergan
Magistrsko delo
Oznake: razredni pouk;prostorske predstave;prepoznavanje objektov;fotografije;opazovanje okolice;domača pokrajina;učenci;
V magistrskem delu smo obravnavali otroške predstave o Ljubljani in domači pokrajini pri učencih treh ljubljanskih osnovnih šol. V teoretičnem delu smo povzeli ključna spoznanja o razvijanju prostorskih predstav pri učencih, njihovem dojemanju prostora in opazovanju okolice oziroma domačega kraja. V ...

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 ...

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 ...

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 ...
