Calculation of the Temperature Distribution in Cylindrical Samples of Alumina and Copper Produced by Spark Plasma Sintering

open access: yesCeramics, 2021
Numerical calculations were carried out to simulate, under conditions of close spark plasma sintering (SPS), the temperature distribution during the passage of current in dense cylindrical samples of two materials: aluminum oxide and copper located in ...

New first order model of thermoluminescence as a function of peak temperature and intensity considering thermal quenching effect [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2023
The thermal quenching effect has not been considered in current research on the first-order kinetics of thermoluminescence. In contrast, thermal quenching as a reality should be contained in theoretical models. In this work, a new fitting function of the

The heating rate impact on parameters characteristic of steel behaviour under fire conditions

open access: yesJournal of Civil Engineering and Management, 2006
The behaviour of steel structure components within a high temperature field depends not only on the absolute temperature, but also on the temperature vs time function and on the heating rate, dT/dτ.

High Heating Rates Affect Greatly the Inactivation Rate of Escherichia coli [PDF]

open access: yesFrontiers in Microbiology, 2016
Heat resistance of microorganisms can be affected by different influencing factors. Although, the effect of heating rates has been scarcely explored by the scientific community, recent researches have unraveled its important effect on the thermal resistance of different species of vegetative bacteria. Typically heating rates described in the literature

Effect of heating rate on sintered series 300 stainless steel [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2010
Stainless steel powders (303L, 304L, 310L and 316L) were formed into tensile test bars using the “press and sinter”process. Most processing parameters, except heating rate, were kept constant. During the heating of the experimental specimensfrom 700°C to
