Thermal explosion of a mechanically activated 3Ni-Al mixture

Results of studying the thermal explosion of 3Ni-Al mixtures after their preliminary mechanical activation in a planetary ball mill are described. Reduction of the initiation temperature and effective energy of activation of interaction between the reagents to anomalously low values is found. Results of an x-ray diffraction analysis and an electron-microscope study of the thermal explosion products and initial mixtures with different times of mechanical activation are given.
