Influence of Deformation on Precipitation Kinetics in Mg-Tb Alloy

Original language description

Precipitation effects in age-hardenable Mg-13wt.%Tb alloy were investigated in this work. The solution treated alloy was subjected to isochronal annealing and decomposition of the supersaturated solid solution was investigated by positron annihilation spectroscopy combined with transmission electron microscopy, electrical resistometry, differential scanning calorimetry and microhardness measurements. Peak hardening was observed at 200oC due to precipitation of finely dispersed particles of ?'' phase with the D019 structure. Vacancy-like defects associated with ?'' phase particles were detected by positron annihilation. At higher temperatures precipitation of ?' and subsequently ? phase takes place. Formation of these phases lead to some additional hardening and introduces open volume defects at precipitate/matrix interfaces. To elucidate the effect of plastic deformation on the precipitation sequence we studied also a Mg-13wt.%Tb alloy with ultra fine grained structure prepared by high
