In this work, the explosion and combustion characteristics of aluminum and some aluminum alloys AlSi7Mg0.6, AlSi10Mg, AlMg5 under powders conditioning were studied. The idea was to compare the combustion of pure aluminum and aluminum alloys. The Minimum Ignition Energy (MIE) and explosion severity ΔP_max and (dP/dt)_max which represents the dust explosion parameters were measured for all powders using Hartman tube and 20 L spherical bomb. The particles temperature and flame temperature were determined by using IR pyrometer and spectroscopy respectively. The results showed that pure aluminum was more sensitive and severe than its alloys. MIE were: 4 mJ for pure aluminum, 13–23 mJ for aluminum alloys. For severity parameters, the overpressure ΔP_max were around 7–8 bars with maximum rate of pressure rise at 1170 bar/s for aluminum and 5–7 bars with 250–360 bar/s for alloys. However, it has been observed that flame temperatures were similar for aluminum and alloys and vary around 2800–3300 K as a function of concentration.

在这项工作中，研究了铝和某些铝合金在粉末条件下的爆炸和燃烧特性。想法是比较纯铝和铝合金的燃烧。最小点火能量（MIE）和爆炸严重性ΔP_最大和（DP / dt）的_最大值，它表示粉尘爆炸参数用于使用哈特曼管和20μL球形炸弹所有粉末进行测定。分别通过使用红外高温计和光谱法确定颗粒温度和火焰温度。结果表明，纯铝比其合金更敏感和更严格。MIE为：纯铝为4 mJ，铝合金为13-23 mJ。对于严重性参数，超压ΔP_最大铝的最大升压速率约为7–8 bar，铝的最大升压速率为1170 bar / s，合金的最大升压速率为250–360 bar / s的5–7 bar。但是，据观察，铝和合金的火焰温度相似，并且随浓度的变化在2800–3300 K左右变化。
