The results of XRD and SEM analyses of the powdershow that Ti_5Si_3 can be synthesized by MA in a planetary mill with two different formationmechanisms. Ti_5Si_3 was formed gradually with the mechanical collusion reaction (MCR) mechanismunder a lower impact energy, and the Ti_5Si_3 was formed abruptly with the self-propagatinghigh-temperature synthesis (SHS) formation mechanism under a higher impact energy.展开更多
