The Effect of Cooling Rate on Microstructure and Mechanical Properties of the Zr-4Hf-3Nb (wt%) Alloy

Metals, 2022
The mechanical properties of Zr-based alloys, such as strength and elongation, are heavily dependent on the cooling rate during heat treatment. Understanding the phase transformation and microstructural evolution in various cooling media can establish ...

Strain Rate Induced Crystallization in Bulk Metallic Glass-Forming Liquid [PDF]

, 2006
We report on the solidification of Au49Ag5.5Pd2.3Cu26.9Si16.3 bulk metallic glass under various strain rates. Using a copper mold casting technique with a low strain rate during solidification, this alloy is capable of forming glassy rods of at least 5 ...

Internal Flow Field and Loss Analysis of a Magnetic Drive Pump’s Cooling Circuit

Energies, 2023
The cooling circuit is an important component of the magnetic drive pump because it prevents demagnetization of the permanent magnet and damage to the containment shell owing to a high temperature increase. In this paper, the flow field and losses of the

A rate equation approach to cavity mediated laser cooling [PDF]

, 2012
The cooling rate for cavity mediated laser cooling scales as the Lamb-Dicke parameter eta squared. A proper analysis of the cooling process hence needs to take terms up to eta^2 in the system dynamics into account.

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

The Effect of Cooling Rate of Cooling System on Centrifuge Machine Performance [PDF]

مجله علوم و فنون هسته‌ای, 2011
In this paper, the effect of cooling rate of a cooling system on performance of a centrifuge machine has been studied experimentally. The cooling rate is increased by temperature variation and volumetric flow rate of the inlet water to the cooling system.

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.

Optomechanical Cavity Cooling of an Atomic Ensemble

, 2011
We demonstrate cavity sideband cooling of a single collective motional mode of an atomic ensemble down to a mean phonon occupation number of 2.0(-0.3/+0.9).
