Cooling-rate effects in a model of (ideal?) glass

, 1999
Using Monte Carlo simulations we study cooling-rate effects in a three-dimensional Ising model with four-spin interaction. During coarsening, this model develops growing energy barriers which at low temperature lead to very slow dynamics.

Extremely low critical cooling rate measured on dispersed Pd43Ni10Cu27P20 [PDF]

, 2002
Crystallization of dispersed Pd43Ni10Cu27P20 melts is studied during constant cooling and heating. Investigations are carried out on samples that are dispersed into several hundred particles which are fluxed in B2O3.

Effect of in situ observation of cooling rates on acicular ferrite nucleation

High Temperature Materials and Processes, 2022
The effect of cooling rates on acicular ferrite (AF) nucleation was observed in situ by laser scanning confocal microscopy. The precipitation characteristics of TiN–MnS inclusions, the austenite grain size, and the content and morphologies of AF were ...

Self-similar collapse with cooling and heating in an expanding universe

, 2003
We derive self-similar solutions including cooling and heating in an Einstein de-Sitter universe, and investigate the effects of cooling and heating on the gas density and temperature distributions.

Phase transition of color-superconductivity and cooling behavior of quark stars [PDF]

, 2001
We discuss the color-superconductivity and its effect on the cooling behavior of strange quark stars. The neutrino emissivity and specific heat of quark matter are calculated within the BCS theory.

Effect of Cooling Rate on the Microstructure and Precipitates of Directional Solidified 50W600 Non-oriented Silicon Steel

High Temperature Materials and Processes, 2013
The microstructure, morphologies of precipitates in directional solidified 50W600 non-oriented silicon steel with three cooling rates (0.095, 0.33 and 4.28 °C/s) were investigated.

Investigation on Continuous Cooling Transformation Process of Low Carbon Bainite Rail Steel U25CrNi by Dilatation and in-situ Observation Method

Teshugang, 2022
By Formastor-F quenching dilatometer thermal simulation and VL2000DX-SVF17SP high temperature laser scanning confocal microscope ( LSCM) observation, the dilatation curve and microstructure of a low carbon bainite rail steel of U25CrNi (/% ：0.25C, 1.73Si,

Quantum speed limit constraints on a nanoscale autonomous refrigerator

, 2018
Quantum speed limit, furnishing a lower bound on the required time for the evolution of a quantum system through the state space, imposes an ultimate natural limitation to the dynamics of physical devices.

Testing the Invariance of Cooling Rate in Gamma-Ray Burst Pulses [PDF]

, 1997
Recent studies have found that the spectral evolution of pulses within gamma-ray bursts (GRBs) is consistent with simple radiative cooling. Perhaps more interesting was a report that some bursts may have a single cooling rate for the multiple pulses that
