摘要：
The explosive decomposition threshold of pentaerythritol tetranitrate was studied depending on the concentrations of ultradispersed Al particles and Ni-C and Al-C mechanocomposites in the samples. It was found that the critical pulse energy density W (0.5), which corresponds to a 50% probability of explosion, reached a minimum value at additive concentrations of 0.1-0.3 wt %: W (0.5) = 1.4, 5, or 4 J/cm(2) for Al, Ni-C, or Al-C, respectively.
