Occurrence of Hysteresis like behavior of resistance of Sb 2 Te 3 film in heating-cooling cycle. Abstract Experimental observations of a peculiar behavior observed on heating and cooling Sb 2 Te 3 films at different heating and cooling rate are detailed. The film regained its original resistance, forming a closed loop, on the completion of the heating-cooling cycle which was reproducible for id...

The combined influence of both melt filtration and cooling rate on the microstructure features and mechanical properties of A356 cast alloy was studied. A step casting model with five different thicknesses was used to obtain different cooling rates. The effect of melt filtration was studied by using of 10 and 20 ppi ceramic foam filters in the runner. Results showed that secondary dendrite arm ...

We examine recent developments in the cluster cooling flow scenario following recent observations by Chandra and XMM-Newton. We show that the distribution of gas emissivity verses temperature determined by XMM-Newton gratings observations demonstrates that the central gas, i.e., where the cooling time is less than the age of the cluster, in cooling flow clusters cannot be in simple steady-state...

Based on the classical Pennes bioheat equation and oxygen diffusion equation, a new coupled heat-mass transfer model for characterizing the cerebral circulatory arrest is proposed. Two cooling approaches (the surface cooling and volumetric cooling) are applied to analyze the effect of hypothermia on the transient temperature and the oxygen consumption rate in different regions of brain. It is s...

A morphological population balance model is applied to crystallisation of hen-egg white lysozyme (HEWL) for investigating the effects of seed loading and cooling rate on supersaturation, crystal size and shape distribution. Growth rates of individual faces and final crystal size and shape distribution were examined under varied seeding and cooling conditions. It was found that for growth only c...

It is well known that the solution cooling rate has a great effect on the creep life of superalloys. In this research, three typical cooling rates were applied to generate different distributions of γ’ precipitates for creep tests. Ingots used to make specimens were manufactured by hot extrusion, and the master alloy had the composition of an FGH4096 power metallurgy superalloy. SEM and SESD we...

Centrifugal atomization is a rapid solidification technique involving fast cooling rates to produce high-quality powders. The final microstructure of the atomized particles closely linked with thermal history and experienced during process. However, there insufficient research on temperature evolution metal produced by this technique, most works evaluate droplet through semi-empirical correlati...
