Prospects for Producing Special Cold-Resistant Economically Alloyed Nickel Ferritic Steel for Liquefied Natural Gas Storage and Transportation Vessels

Metallurgist - Ferritic steels are developed economically alloyed with nickel (up to 7%) with increased strength and low-temperature toughness for the manufacture of liquefied natural gas (LNG)...     

Steels for Bridge Structures

Metallurgist - We consider domestic and foreign standards for rolled metals used in bridge building. Domestic standards contain elevated requirements to the reliability of rolled metals in terms of...     

Investigation of Stimulated Emission from HgTe/CdHgTe Quantum-Well Heterostructures in the 3–5 μm Atmospheric Transparency Window

Semiconductors - Stimulated emission based on interband transitions depending on the pumping wavelength is studied for heterostructures with Hg(Cd)Te/CdHgTe quantum wells in the wavelength region...     

Structure–phase state of the surface layers in rails subjected to differential hardening

A layer-by-layer analysis of the structures, the phase compositions, and the defect substructures of differentially hardened rails has been carried by optical and transmission electron microscopy. It is found that the material volume of the rail head fillet is cooled faster than the volume located along the central axis.     

Calculation of Wave Functions of Resonant Acceptor States in Narrow-Gap CdHgTe Compounds

Semiconductors - Electron wave functions in the conduction band of zero-gap HgCdTe alloy are calculated in the Coulomb acceptor field. The resonant-state energies are determined.
