Thermo-analytical experiments were used to characterize prepared Al?Mg and Al?Ti powders. Ignition temperatures for the Al?Mg powders vary from approximately 860 to 1060 K for the range of heating rates covered in the present ignition experiments. Kinetic correlations using Kissinger analysis were made to identify the reactions that may cause or contribute to ignition. Ignition for both Al?Mg and Al?Ti powders is associated with low-temperature, sub-solidus reactions. Discovery差示掃描量熱儀 Discovery 熱重分析儀
