Research Progress on High-Temperature Oxidation and Corrosion Mechanisms of Aluminide Coatings [PDF]
Cailiao Baohu, 2023 Aluminide coatings are widely used to protect engine hot-section components such as turbine blades， but during service， they are prone to high-temperature oxidation and hot corrosion，resulting in failure.Aiming at the failure of aluminide coatings in ...

Infinite Temperature's Not So Hot
, 2022 It has been argued that the entanglement spectrum of a static patch of de Sitter space must be flat, or what is equivalent, the temperature parameter in the Boltzmann distribution must be infinite. This seems absurd: quantum fields in de Sitter space have thermal behavior with a finite temperature proportional to the inverse radius of the horizon.

Automatic Control of Hot Metal Temperature
Metals, 2022 To achieve the automation of blast furnace operation, an automatic control system for hot metal temperature (HMT) was developed. Nonlinear model predictive control (NMPC) which predicts up to ten-hour-ahead HMT and calculates appropriate control actions ...

Equivalent temperature of hot electrons
Solid-State Electronics, 1980 Abstract The two extensions of the Einstein relation qDpar = kTeμpar and qDpar = kT′eμ′and define, in the case of hot electrons, two different electron temperatures Te and T′e. It is shown here that the two interpretations are fully equivalent in that they lead to the noise expressions S I (0)=4kT( I V and S I (0) = 4kT′ e (

No pause in the increase of hot temperature extremes
, 2014 Observational data show a continued increase of hot extremes over land during the so-called global warming hiatus. This tendency is greater for the most extreme events and thus more relevant for impacts than changes in global mean temperature.
