Methods are proposed for regulating the reactivity of energetic materials that circulate in the technosphere and are not rarely the cause of fires and explosions, both during storage and during transportation. As man-made factors that influence the stability of these materials magnetic and temperature fields and mechanical effects were used. The magnetic field (in the range from 0.01 T to 0.3 T) was used to intensify chemical processes, both at the stage of crystal growth (by the example of silver azide) and together with mechanical action (from 10 5 Pa to 10 7 Pa) in the finished crystals. The action of the magnetic field and mechanical stress leads to the stimulation of microplasticity and macroplasticity processes, which are accompanied by a slow decomposition of the samples and subsequent destruction. It was established experimentally that a slight change in storage temperature, as compared to room temperature, accelerates the aging process of samples (range of positive temperatures up to + 30°C), or leads to loss of plasticity (range of negative temperatures down to -20°C) resulting in loss of performance and in loss of useful properties of energy materials.
