Abstract:
Thanks to the specific sensitivity of lead to volatile organic compounds (VOC), it is possible to use lead as an indicator of contamination of the indoor atmosphere of depositories of archives and museums where VOCs are typical pollutants. The classification of corrosion aggressiveness of indoor environments based on the determination of the corrosion rate of reference metals is given by the standard ISO 11844-1 which was recently supplemented with lead.

Abstract:
Orthorhombic Ti2AlNb-based alloys are considered as promising materials for high-temperature applications in aero-engines due to their high yield strength, low-cycle fatigue, creep resistance. Additive manufacturing is a promising way of producing intermetallic alloy since it allows obtained complex-shaped parts without significant machining. [..]

Abstract:
Ti2AlNb-based titanium matrix composites reinforced by silicon carbide particles/fibers have received great attention for light-weight aero-space applications at high service temperatures since titanium orthorhombic alloys demonstrate an attractive combination of mechanical properties, low density, and are suitable for matrix materials. Additive Manufacturing is a promising way of producing SiC/Ti2AlNb composites because it offers a possibility to produce parts with ahigh degree of design-freedom and good mechanical properties. [..]

Abstract:
The quality control of most castings concerns finished products and is carried out at special stands after the end of the production process. However, more and more foundries decide to use the so-called inter-operational quality control, the advantage of which is the earlier detection of defective products, which allows, among others to reduce production costs.
