摘要:
The formation mechanism of stoichiometry Ti
5Si
3 by mechanical alloying (MA) from elemental powders has been investigated. The results of XRD and SEM analyses of the powder show that Ti
5Si
3 can be synthesized by MA in a planetary mill with two different formation mechanisms. Ti
5Si
3 was formed gradually with the mechanical collusion reaction (MCR) mechanism under a lower impact energy, and the Ti
5Si
3 was formed abruptly with the self-propagating high-temperature synthesis (SHS) formation mechanism under a higher impact energy.
