The authors conducted experiments that monitored the response of heated, confined energetic materials in both fixed-volume and fixed-load configurations. They studied a variety of HMX-based materials, looking at the effects of particle size and binders. The {beta}-{delta} phase transition near 170 C led to a more reactive state. Materials that underwent complete transition in the fixed-load experiments (allowed to expand fully to accommodate the 5% volume increase) cooked off faster than those in the fixed-volume configuration
