Abstract

In this study, the dependences of the velocities and maximum combustion temperatures on the initial temperature for initial and mechanically activated Ti + Ni mixtures are determined. For activated mixtures, the transition temperatures from the layer-by-layer combustion to the thermal explosion mode are established. The maximum heating temperatures during a thermal explosion are determined. Observations were made of changes in the appearance and phase composition of burnt samples at different initial temperatures and during the transition from the combustion mode to the thermal explosion mode. It was found that in the case of the initial mixture, in the entire investigated range of initial temperatures, combustion occurs with the formation of a liquid phase in the layer-by-layer combustion mode. In the case of activated mixtures, a solid-phase synthesis mode is realized both in the combustion mode and in the thermal explosion mode.

摘要

在这项研究中，确定了初始和机械活化的Ti + Ni混合物的速度和最高燃烧温度对初始温度的依赖性。对于活化混合物，建立了从逐层燃烧到热爆炸模式的转变温度。确定热爆炸过程中的最高加热温度。在不同的初始温度下以及在从燃烧模式到热爆炸模式的转变过程中，观察了燃烧样品的外观和相组成的变化。发现在初始混合物的情况下，在整个研究的初始温度范围内，燃烧随着层状燃烧模式下的液相形成而发生。如果是活性混合物，
