“…According to the two equations, plots of versus 1/ T p and log β versus 1/ T p should result in straight lines, the slope of the straight line is equal to − E a / R and then E a can be calculated. Besides, frequency factor A can be calculated by the following equation 30,32 The Kissinger and Ozawa plots obtained for the intensive oxidation of the Al–20Mg–2Zr alloy powder are shown in Fig. 7.…”

A novel ternary alloy with the composition of Al–20Mg–2Zr (wt-%) was prepared by close coupled gas atomisation. The thermal oxidation behaviour of the powder was examined by thermogravimetry–differential thermal analysis. The results showed that the oxidation proceeded in single step, and the violent exothermic reaction occurred after 900°C was almost complete. The activation energy of the oxidation was ∼250 kJ mol− 1, and the frequency factor was ∼1.47 × 1011 s− 1 and 3.36 × 1011 s− 1 using the Kissinger and Ozawa method respectively. The special feature of the pulsed oxidation was explained by the melt dispersion oxidation mechanism. The excellent thermal reactivity exhibited by the Al–20Mg–2Zr powder suggested that this novel alloy could become one of the most promising materials in energetic applications.
