Times Cited Count:1 Percentile:16.17(Chemistry, Physical)Phase equilibria in the Mn-Zn binary system were experimentally determined by chemical composition examination, crystal structure determination, and thermal analysis. Major changes were detected for the ,
, and
phases. The
-B2 single-phase region could not be confirmed in the studied system because a disordered body-centered cubic structure, which is identical to the
Mn phase, was confirmed in a quenched sample from the previously proposed region of
phase. The
phase has been controversial whether the phase is separated into
,
, and
phases or not. By studying a diffusion couple and several alloy compositions, it was established that the
,
, and
phases are not separate and comprise a single
phase. Furthermore, the
phase is not present in the Zn-rich region of the system because the corresponding invariant reactions were not detected via thermal analysis.

Authors developed a radiotracer method for diffusion studies in solids. The experimental test was performed by the measurement of the diffusion coefficients of Li in a sample of the compound LiAl using an
-emitting radiotracer of
Li(T
= 0.84 s). It was found that the time-dependent yields of the alpha particles from the diffusing 8Li that was initially implanted in the sample could be used as a measure of the diffusivity of the tracer in a nondestructive way. The method was applied to measure the self-diffusion coefficients of Li in
LiGa, and for investigating how the Li diffusion in the Li ionic conductors is affected by the concentration of atomic defects.
