The annealing and re-annealing of glass [PDF]

Transactions of the Optical Society, 1924
In Part III of this paper the formulae deduced in the previous parts are applied to the case of heating glass under constant gradient and the temperature at which strain disappears is obtained, the effect of the known change in the coefficient of expansion on this temperature being discussed.

Optimization of glass annealing

Glass and Ceramics, 1997
An algorithm was developed for calculating optimal glass annealing schedules for batch-type and continuous annealing units subject to the capabilities of a particular unit and the constraints imposed by temporary and residual stresses. The criterion chosen for the optimization is the throughput of the annealing unit which is in turn determined by the ...

Thermal stress modification in regenerated fiber Bragg grating via manipulation of glass transition temperature based on CO₂-laser annealing.

Optics Letters, 2015
In this work, we have demonstrated thermal stress relaxation in regenerated fiber Bragg gratings (RFBGs) by using direct CO₂-laser annealing technique. After the isothermal annealing and slow cooling process, the Bragg wavelength of the RFBG has been red-

Note on the Annealing of Glass

Journal of Applied Physics, 1943
The rate of removal of mechanical strain should follow Maxwell's first-order law, but for glasses it has been found that the rate is proportional to the square of the birefringence. The present paper explains this in terms of the structural picture of glass.

Scaling Advantage in Approximate Optimization with Quantum Annealing.

Physical Review Letters
Quantum annealing is a heuristic optimization algorithm that exploits quantum evolution to find low-energy states. Quantum annealers have scaled up in recent years to tackle increasingly larger and more highly connected discrete optimization and quantum ...

Annealing control for sheet glass

Glass and Ceramics, 2012
Neutral net models of the annealing of a moving ribbon of sheet glass in a tunnel furnace are developed. The problem of controlling the annealing temperature regime is formulated. Simulation modeling is used to show that the control algorithm is more efficient than manual control of the annealing process. The implementation of a decision-making support

Sub-glass transition annealing enhances polymer solar cell performance

, 2014
Thermal annealing of non-crystalline polymer:fullerene blends typically results in a drastic decrease in solar cell performance. In particular aggressive annealing above the glass transition temperature results in a detrimental coarsening of the blend ...

Annealing and Glass Transition of Starch

Starch - Stärke, 1986
AbstractThe enthalpy of the order‐disorder transition of starch increased as the starch hydration period was increased from 1 h to 24 h. This was explained as the exothermic heat of hydration cancelling part of the endothermic heat of melting. Annealing of starch was shown to occur at 3 to 8°K below the Tm of starch.
