Sažetak
The temperature dependence of microstructure in Zn-Al alloys, transferred
to the equilibrium state by quenching from the solid solution temperature,
(T)SS, to room temperature (RT) and prolonged ageing at RT, was studied in
situ by X-ray powder diffraction. Instead of the phase transitions expected
according to the phase diagram, namely (alpha(M/beta) + beta) to (alpha'
+ alpha(M/alpha')) to alphaSS for the alloy with 54 at% Zn, and (alpha(M/
beta) + beta) to (alpha' + beta) to alphaSS for the alloy with 62 at% Zn,
the following sequence was observed for both alloys:(alpha(M/beta) + beta)
to (alpha' + beta + alpha(M/alpha',beta)) to (alpha'+ beta) to alphaSS. In
the cooling run, a temperature hysteresis in reversal phase transitions was
observed. During a repeated heating, the microstructure depended on the
previous thermal treatment of the alloys.
