The decomposition of β-solid solution in the alloys of Zr with Nb, Mo, Al, V

X-Ray diffraction analysis of mono- and polycrystals and electron microscopy are employed for investigating the structural mechanism and kinetics of precipitation of ω and α phases and ZrMo$_{2}$, Zr$_{3}$Al, and ZrV$_{2}$, intermetallic compounds from а β solid solution. It is found that an ordered ω$_{2}$ phase is precipitated from an ordered body centered cubic of the β solid solution in the Zr-Mo-Al alloy.
