摘      要：Based on the results of electron probe microanalysis(EPMA)and X-ray diffraction(XRD),the isothermal sections of Zr-Ni-Ge ternary system at 973 K and 1173 K were constructed through alloy sampling *** is worth noting that the crystallographic information of the formerly reportedτ2(Zr_(0.98)NiGe_(2.94))was determined,which belongs to the space group Pbcm(No.57).Besides the formerly reported ternary compounds,τ1(Zr_(6)Ni_(16)Ge_(7)),τ_(2)(Zr_(0.98)NiGe_(2.94)),τ_(3)(Zr_(3)Ni_(4)Ge_(4)),τ_(4)(ZrNiGe)andτ_(5)(Zr_(2)Ni_(0.54)Ge_(0.46)),a new ternary phase namedτ_(6)with the composition of Zr_(39)Ni_(18)Ge_(43)was primarily detected in this *** addition,an invariant reaction Ni_(5)Ge_(3)+τ_(4)τ_(1)+τ_(3)between 973 K and 1173 K was deduced.
