Only Formation of ZrAl3 Phase Obtained by Self-Propagating Reaction from Zr-Al Elemental Powders
In this paper, the problem of ZrAl3 compound obtained by self-propagating reaction as the only and favorable formation phase was considered. It shows that the ZrAl3 phase could be synthesized by self-propagating reaction in Zr-Al system and was especially identified as the only phase by XRD, which was further confirmed by DTA. Using the theories of structural lattice of ZrAl3, Modified Effective Heat of Formation (MEHF) model, coupled with the First Nucleation Rule (FNR), the only formation of ZrAl3 phase in Zr-Al system could be reasonably interpreted.
