High-Temperature Mechanical Behavior of Cobalt-Free FeMnCrNi(Al) High-Entropy Alloys

open access: yesMetals, 2023
The high-temperature properties of new alloys need to be investigated to guide the hot working process. The temperature sensitivity of various microstructures of Fe45Mn15Cr15Ni25 and Fe35Mn15Cr15Ni25Al10 cobalt-free high-entropy alloys was investigated ...

Entropy [PDF]

open access: yesEncyclopedia, 2009
The concept of entropy constitutes, together with energy, a cornerstone of contemporary physics and related areas. It was originally introduced by Clausius in 1865 along abstract lines focusing on thermodynamical irreversibility of macroscopic physical processes. In the next decade, Boltzmann made the genius connection—further developed by Gibbs—of the

Memory and Entropy

open access: yesEntropy, 2022
I study the physical nature of traces. Surprisingly, (i) systems separation with (ii) temperature differences and (iii) long thermalization times are sufficient conditions to produce macroscopic traces. Traces of the past are ubiquitous because these conditions are largely satisfied in our universe.

Holographic derivation of entanglement entropy from the anti-de Sitter space/conformal field theory correspondence. [PDF]

open access: yesPhysical Review Letters, 2006
A holographic derivation of the entanglement entropy in quantum (conformal) field theories is proposed from anti-de Sitter/conformal field theory (AdS/CFT) correspondence.

Comparative study on surface oxygenation and widening of carbon fibers made electrochemical electrodes

open access: yesAIP Advances, 2023
Polarity and surface area are two important factors in determining electrochemical performance and are here studied systematically using carbon fiber cloths (CFCs) as electrodes. The CFC polarity is enhanced by plasma treatment that creates polar groups,

Cryogenic strength improvement by utilizing room-temperature deformation twinning in a partially recrystallized VCrMnFeCoNi high-entropy alloy

open access: yesNature Communications, 2017
CrMnFeCoNi high entropy alloys have high fracture toughness at cryogenic temperatures due to deformation twinning but twinning is not active in this alloy at room temperature. Here authors optimize composition and thermomechanical treatments to introduce
