Abstract:
The Hedvall effect was implemented in self-propagating high-temperature synthesis (SHS) in two low-energy compositions $\mathrm{TiNi}+1.1\mathrm{C}$ and $\mathrm{Ni}_3\mathrm{Al}+1.2\mathrm{Si}$ using preliminary mechanical activation (MA) in an energy-intensive planetary ball mill. The dependences of the initiation temperature and the maximum reaction temperature on the MA time were obtained. The MA modes providing the solid-state mode of the self-propagating reaction were determined. The results of X-ray phase and electron microscopic examination of MA and SHS products are given.
Keywords:
Hedvall effect, self-propagating high-temperature synthesis, mechanical activation.
