Crystallization Behavior of Bisphenol-A Polycarbonate: Effects of Crystallization Time, Temperature, and Molar Mass
… secondary crystallization model. During isothermal annealing of semicrystalline PC-28K around the high melting endotherm, a significant increase of melting temperature along with peak broadening with time was observed. Independently, morphological studies using AFM showed that mean …

Characterization and optimization of polyethylene blends
… or a metallocene-catalyzed LLDPE. A two-step isothermal annealing (TSIA) procedure is developed enabling the satisfactorily resolution of endothermic peaks of blends of low-density polyethylene with LLDPE using standard thermoanalytical techniques. The TSIA procedure enables the quantification …

Directional Recrystallization of an Additively Manufactured Oxide Dispersion-Strengthened Nickel-Base Superalloy
… specifically on the effects of a liquid phase, annealing twins, and aluminum microalloying additions on recrystallization kinetics. Conventional wrought ODS alloys achieve coarse columnar grains through directional recrystallization (DRX) heat treatments. The main goal of this study was to …

Hot formability and microstructural development of spray-deposited Al-Li alloy and composite.
… also provided high temperature ductility data. Isothermal annealing of rolled samples was carried out at the solution temperature of 530°C to investigate the recrystallisation kinetics and microstructures produced, with particular emphasis on the effect of the inclusion of reinforcement …

Transition metal gettering studies and simulation for the optimization of silicon photovoltaic device processing
… heat treatments are ramps up in temperature, isothermal annealing, and cools from high temperature down to room temperature. We explore a range of surface conditions, density and size of heterogeneous nucleation sites in the bulk, and the degree of contamination in order to create a framework …

Mechanisms and Implementation of Thermo-Optical Annealing in Silica Fiber Sensors for Radiation-Induced Attenuation Mitigation
… and assess strategies for mitigation, namely, annealing via heat treatment (thermal annealing) and annealing via light propagation through the fiber (optical annealing, or “photobleaching”). We design a white light absorption spectroscopy setup with in-situ irradiation and optical annealing, …

Pattern Formation and Phase Behavior in PS-B-SI Containing Block Copolymer Thin Film
… and can be stabilized during thermal annealing up to 200 oC. This unusual high meta-stability can be attributed to the large ¿ value between PS and PDMS blocks thus result in a high energy barrier for morphology transition. In the contrast, a unique structure evolution route was …

Bonding Characteristics and Devitrification Behavior in Iron-Containing Sodium-Silicate Glasses
… phase has already formed after isothermal annealing between 515(DEGREES)C and 700(DEGREES)C. However, when the annealing temperature (>700(DEGREES)C) is high enough to rearrange those polyhedra, the Fe(,2)O(,3) and Na(,5)Fe(SiO(,3))(,4) precipitates will result. Most of the iron …

THE INTERPLAY BETWEEN CATION ORDERING AND ELASTICITY OF OMPHACITES TO UNRAVEL PTT PATHS OF METAMORPHIC ROCKS
… degrees of cationic-site order achieved through isothermal annealing experiments, it was observed that increasing cationic disorder leads to peak broadening, whereas pressure variations influence Raman peak positions, and the magnitude of these changes was quantified. However, the peak position …

Microplasticity in metallic glasses
… is used to probe the structural dynamics during isothermal annealing all the way to the onset of crystallization. These complementary studies are substitutes for scheduled in-situ mechanical experiments that could not be realized due to the COVID-19 pandemic. Approaching macroscopic yielding, AE …
