Abstract
Discontinuous precipitation in a two-phase Zn-rich Zn-6.3 at.% Ag alloy has been studied. It has been shown that the eta'/epsilon interphase boundarie s have the ability to initiate discontinuous precipitation as do the eta'/e ta' grain boundaries. The back-polishing method is used to show the interco nnection between a discontinuous precipitate colony and the eta'/epsilon in terphase boundary. The reaction front velocity of discontinuous precipitati on initiated at the eta'/eta' grain boundary is 12-90% higher than that of discontinuous precipitation initiated at the eta'/epsilon interphase bounda ry under various ageing temperatures.
