Effect of carbon content in a Ni–Al–C system and preliminary mechanical activation on a burning rate, sample elongation, and mixture yield after mechanical activation, as well as on the structural features of combustion products is under study. Combustion in pressed samples from a mechanically preactivated Ni + Al mixture at room temperature could not be activated. The addition of carbon [2, 4, and 6% (by weight)] into the reacting Ni + Al mixture allows for combustion in Ni–Al–C based pressed samples. Preliminary mechanical activation of the reacting Ni + Al + xC mixture expands a carbon content limit in the mixture at which the combustion of pressed samples is possible. In addition, mechanical activation, as well as an increase in the carbon content in the Ni–Al–C system reduces the burning rate. The observed relationships are explain.

含量和机械活化对 Ni-Al-C 体系燃烧的影响

Ni-Al-C 体系中的碳含量和初步机械活化对机械活化后的燃烧速率、样品伸长率和混合物产率的影响，以及对燃烧产物结构特征的影响正在研究中。室温下机械预活化的 Ni + Al 混合物在压制样品中的燃烧无法激活。将碳 [2、4 和 6%（按重量计）] 添加到反应的 Ni + Al 混合物中，可以在基于 Ni-Al-C 的压制样品中燃烧。反应性 Ni + Al + xC 混合物的初步机械活化扩大了混合物中的碳含量限制，在该限制下，压制样品可能燃烧。此外，机械活化以及 Ni-Al-C 系统中碳含量的增加会降低燃烧速度。观察到的关系得到解释。
