This paper presents the chemical and phase composition, microstructure, selected properties both at room temperature corresponding to expected operating conditions of three successive generations TiAl-based alloys (Ti-47Al-2W-0.5Si, Ti-45Al-8Nb-0.5(B,C), Ti-45Al-5Nb-2Cr-1Mo-0.5(B,C)-0.2Si) melted in a vacuum induction furnace with high-density isostatic pressed graphite crucibles. The obtained ...

In an article about the importance of choice materilas, harmful impurities in synthetic cast iron, amd improving strength characteristics which requires a new method smelting iron using steel scrap as charge corrresponding crucible furnaces, presences metal charge, together with pig return own production, carburetors, and ferroalloys for purpose carburizing alloying to required chemical composi...

This study examined gene expression changes associated with exertional heat injury (EHI) in vivo and compared these changes to in vitro heat shock responses previously reported by our laboratory. Peripheral blood mononuclear cell (PBMC) RNA was obtained from four male Marine recruits (ages 17-19 yr) who presented with symptoms consistent with EHI, core temperatures ranging from 39.3 to 42.5 deg...

The article describes new approaches to calculating the thermal regimes of induction crucible furnaces, as well methods for them using converted circuits. principles constructing models structural parts and molten metal furnaces based on ETS their use development optimal systems automatic control melting process are considered. methodology compilation heat balance equations with a capacity up 1...

The present paper discusses the Simulation Experience Design Method employed to create engaging learning environments for training U.S. Armed Forces to think adaptively. This design method is based on the notion that one’s total experience in the simulated environment, or crucible, is integral to the learning process. A “crucible” experience is a defining moment that unleashes abilities, forces...
