The stability of the Johnson-Mehl-Avrami equation parameters
The stability of the parameters of the Johnson-Mehl-Avrami equation was studied using two parametrizations of the sigmoidal function and its fit to some kinetic data. The results indicate that one of the forms of the ...
Ag precipitation and dissolution reactions in the Cu-3 wt.% Al-4 wt.% Ag alloy
(Elsevier B.V., 2006-12-15)
The Ag precipitation and dissolution reactions in the Cu-3 wt.% Al-4 wt.% Ag alloy were studied using isothermal and non-isothermal analyses. The activation energy values, obtained for the Ag precipitation reaction indicated ...
Kinetics of eutectoid decomposition in Cu-Al and Cu-Al-Ag alloys
(Elsevier B.V., 1997-08-01)
The kinetics of eutectoid decomposition beta(1)' --> gamma(2) + (alpha + gamma(2)) in Cu-12.86 wt% Al and Cu-12.84 wt% Al-1.98 wt% Ag alloys was studied by hardness measurements, using the Johnson-Mehl-Avrami equation. The ...
Chlorination of Lanthanum Oxide
(American Chemical Society, 2012-02)
The reactive system La2O3(s)−Cl2(g) was studied in thetemperature range 260−950 °C. The reaction course was followed bythermogravimetry, and the solids involved were characterized by X-raydiffraction, scanning electron ...
Methods to estimate the number of surface nucleation sites on glass particles
(Soc Glass Technology, 2008-04-01)
Based on the Johnson-Mehl-Avrami-Kolmogorov (JMAK) theory, we propose two new models to describe the crystallisation kinetics of glass particles and use them to determine the density of nucleation sites, N(s), on glass ...
