Recycling of steel chips
Matjaž Torkar, Martin Lamut, Agron Millaku
Strokovni članek
Oznake: steel chips;magnetic separation;cold compaction;remelting;
The recycling of waste metallic materials and the use of scrap are important for the economic production of a steelworks. Here, we investigate the technology of remelting steel chips. It was confirmed that the main problems with using chips in an electric arc furnace were the chips' large specific s ...

An AES investigation of brushed AISI 304 stainless steel after corrosion testing
Matjaž Torkar, Djordje Mandrino, Martin Lamut
Strokovni članek
Oznake: stainless steel;pitting corrosion;passivation;deformation-induced martensite;AES analysis;
During a test in a wet salt (NaCl) chamber rusty spots and elongated pits appeared on the brushed surface of a prototype casing for a household device made from AISI 304 stainless steel. The corrosion pits only formed on the brushed surface and on the deformed edges. Metallography revealed deformati ...

Physical properties of mineral fibers depending on the mineralogical composition
David Bombač, Martin Lamut, Primož Mrvar, Brane Širok, Benjamin Bizjan
Izvirni znanstveni članek
Oznake: mineral wool;fibers;chemical composition;mechanical properties;nanoindentation;
A developed methodology for determining the physical properties of mineral fibers prepared from different input mixtures under the same spinning wheel conditions is described and discussed. Energy dispersive X-ray fluorescence spectroscopy was combined with simultaneous thermal analysis and thermogr ...

Elastic and plastic deformation of surface asperities and their load-carrying mechanisms during the formation of a real contact area
Mitjan Kalin, Blaž Brodnik Žugelj, Martin Lamut, Karim Hamouda
Izvirni znanstveni članek
Oznake: in-situ asperity experiment;multi-asperity contacts;real contact area;work-hardening;deformation;steel;roughness;
How the contact behaviours of steel engineering surfaces with different roughnesses (R$_a$ = 0.1, 0.6 and 1.0 µm) are affected by the asperity work-hardening and the deformation regime are described here. Large values of the plasticity index Ψ between 20 and 50 indicate that all the surfaces should ...

Degradation processes of two compound layers on nitrided surfaces during the wear test by ‘‘block on hot al cylinder’’
Martin Lamut, Jaka Burja, Milan Terčelj, Goran Kugler, David Bombač
Izvirni znanstveni članek

The results obtained in the study help to explain the degradation process of the nitrided steel compound layer. Compound layers with different properties on gas-nitrided H10 tool steel blocks were tested for wear with ‘‘block on hot Al cylinder’’. Degradation processes were observed on both compound ...
