Abstract:
A new method is proposed to estimation of hydrogen pressure in equilibrium with hydride phase in a hydrogen storage material. It is applicable both for hydrogen absorption and desorption in cases where the hydride phase is formed by nucleation and growth mechanism. [..]

Abstract:
Sintered permanent magnets based on the Nd2Fe14B intermetallic compound are widely used in industry as a rule in a temperature range of from -60 to 150 °C. However, in recent years, there appears a need to use such magnets at cryogenic temperatures and mainly at liquid nitrogen temperature (77 K). [..]

Abstract:
Powder bed techniques of additive manufacture, where the built product is surrounded by a loose powder, yield low-quality surfaces. The powder particles that are in a close contact with the product adhere to its surface, either by thermal diffusion effects or by partial melting by contour scan tracks. [..]

Abstract:
Current tin recovery processes from steel sheets of scrapped cans are mainly based on hydrometallurgical methods using water solutions of acids and bases. Due to the universally binding tendency forcing activities aimed at improving the efficiency of production processes, also in the case of hydrometallurgical methods of metal recovery, it is necessary to look for new economic technological solutions.

Abstract:
Computed Tomography (CT) as a known medical research method is nowadays widely used in research institutions and production companies. Due to its nondestructive testing nature, CT finds application in both final product quality control such as castings or CNC machined parts and research of new materials, e.g. [..]

Abstract:
An important role in the investment casting process is played by the surface condition of the first coating of a multi-layer ceramic mould, as it directly affects the quality of the obtained cast. In industrial conditions, it is not possible to assess surface quality of the first ceramic mould cover without breaking it. [..]
