Aging precipitation and recrystallization of rapidly solidified Cu–Cr–Zr–Mg alloy

In this paper, the recrystallization process during aging for a rapidly solidified Cu–Cr–Zr–Mg alloy has been investigated. It is found that the discontinuous crystallization process has been partially retarded by the ultra-fine and dispersed precipitation upon aging after deformation. Thus, a phenomenon of combined in situ and discontinuous recrystallization has been observed in the rapidly solidified Cu–Cr–Zr–Mg alloy. On the nucleation and growth of recrystallization, the precipitated phases are coarsened and dissolved in the front of grain boundaries following a re-precipitation in the recrystallization area,which results in the much more dispersed precipitates.
