Titanium and its alloys, particularly Ti6Al4V, are widely used, especially in aerospace andmedicine due to their relatively low density, high strength, and good corrosion resistance. However,there are formidable challenges in casting, forming, and machining titanium alloys, which result infinal products that are considerably more expensive. Additiv...

The mechanical properties and microstructure of copper base shape memory alloys are relatively well known, while data on thermal properties (thermal conductivity, specific heat, and temperature conductivity) are not available. In the frame of our investigation work thermal properties of rapidly solidified Cu-Al-Ni-Mn alloy were deter...

The presented investigation work investigates thermal properties of the ultra-high hardness (UHH) armour steel. Steel is distinguished with high hardness and strength. It is sold in the quenched or tempered state, because achieving planned hardness which has to be between 590 HB and 640 HB. In the frame of the investigation work the analysis of the...

FeCrAl alloys are used in a wide range of resistance and high-temperature applications such as wire heaters, furnace structure parts, etc. Their oxidation resistance at elevated temperatures relies on the formation of a thin and a continuous Al2O3 layer on the alloy surface. Growth and thickness of the protective Al2O3 layer depends ...

The most used and established method for detecting the effects of the product on the environment is a life cycle assessment (LCA) method. LCA analyzes the effects of the product on the environment in its all five life stages: design, materials selection, manufacture, use, and ultimately its removal. At the same time LCA is an important tool wh...

Innovative idea of the device for detecting microstructure changes, concept and construction was carried out and controlled by authors of this article in cooperation with Slovenian industry. Since the electrical resistance is one of the most structurally sensitive properties of the materials, we used its measurement to detect microstructural change...
