The presence of different microstructures along pre-crack fatigue fronts has important effects on the critical crack tip opening displacement (CTOD). This value is the relevant parameter for the safe servicing of energy components (penstocks). In the case of specimens with a through thickness notch ...

Wood-burning boilers are a popular source of heating in Slovenia. However, there has been much debate about the potential negative health effects associated with wood smoke in recent years. Wood smoke is increasingly seen as a significant component of airborne particulate matter (PM), especially in ...

Rust-resistant metals, such as the popular stainless steel, often contain some quantities of delta ferrite that lower the mechanical properties of welded joints. The results of the study show that the amount of ferrite influences the quality assessment of austenitic stainless steel welds for the pro ...

Commercially pure (CP) titanium was surface modified with nitrogen-, argon- and oxygen-ion implantations in order to investigate the material's corrosion resistance in a simulated body fluid. Five doses were chosen for the ions, ranging from 5.1015 cm-2 to 2.5-1017 cm-2. In-vitro open-cyclic potenti ...

Problematika varivosti malolegiranih konstrukcijskih jekel se kaže tudi v fenomenu razpokljivosti v hladnem. V raziskavi je namenjena posebna pozornost nastajanju razpok v hladnem v večvarkovnem strjenem varu. Razpokljivost v hladnem v strjenem varu preprečujemo s predgrevanjem, za zagotovitev ustre ...

Razlike mehanskih lastnosti med posameznimi področji vara vplivajo na porazdelitev plastičnih deformacij na konici razpoke že med izvajanjem lomno mehanskega preizkušanja in s tem tudi na velikost lomne žilavosti. Spremembe omejevanja plastične deformacije med lomnomehanskim preizkušanjem še dodatno ...
