The combustion characteristics of ultrafine Al‐Mg alloy powder particles, produced by mechanical alloying methods, and sieved to well‐defined size ranges (35 to 100 μm) were investigated. The ignition and burning times and their size‐dependence were determined using time‐resolved images of particles burned in the post‐flame zone. It was observed that both the ignition and burning times increased with increasing particle size.
