The oxygen diffusion and microstructure were investigated in specimens of commercial Non Evaporable Getter under the trademark of St 707, which is an alloy of Zr(70)-V(24.6)-Fe(5.4) using EDS, AES and XRD. Specimens were in the form of tablets compressed from St 707 powder of typical particle size f ...

Thin solid films appear most commonly in polycrystalline form, which means that they have higly constrained single-crystalline grains. Polycrystalline films are used in a large variety of devices, such as magnetic storage media, catalytic and thermal elements, protective coatings. It is thus desirab ...

This work investigates the influence of the direct laser texturing at high fluences (DLT-HF) on surface mor - phology, chemistry, and wettability. We use a Nd:YAG laser (gamma= 1064 nm) with pulse duration of 95 ns to process stain- less steel surface. The surface morphology and chemistry after the ...

The microstructural evolution of a Fe-Mn-Al-Ni-C low-density steel was studied. The lightweight low-density steels are a promising material for the transportation industry, due to their good mechanical properties and low density. The base microstructure of the investigated steel consists of ferrite ...

Lightweight Fe-Mn-Al-C steels have low density, and high mechanical properties, which makes them a possibility for weight reduction in vehicles for road transport. In steel production, as-cast microstructure is an important parameter for further processing. The as-cast microstructure of five lightwe ...

We studied the effect of isothermal annealing (600–750 °C, 1 to 1000 min) on the microstructure
and mechanical properties of SAF 2205 duplex stainless steel. Impact toughness was found
to be significantly more affected than hardness by annealing. Annealing at 750 °C for 1000 min
resulted in a more t ...

This paper gives an overview of findings, connected with metallurgical activity, at the Pržanj archeological site near Ljubljana, Slovenia. More than 230 kg of slag and other remains connected with early medieval (from the 5th to the 12th century AD) metallurgical activities was found at the excavat ...

Predstavljena je rekonstrukcija tehnološke poti izdelave bronaste čelade iz pozne železne dobe. Bronasta čelada je bila najdena v kraju Podzemelj v Beli Krajini ter spada med eno najpomembnejših najdb na Slovenskem zadnjih let. Original čelade se nahaja na stalni razstavi v Belokranjskem muzeju v Me ...

The production of clean steel is associated with high-quality steel grades for demanding applications. The formation of oxide inclusions mainly depends on the deoxidation practice; it is usually carried out through Al additions, but alumina inclusions can have detrimental effects. An alternative zir ...
