Dynamic recrystallization during hot compression of as-cast and homogenized noncombustible Mg–9Al–1Zn–1Ca (in mass%) alloys

As-cast and homogenized Mg–9Al–1Zn–1Ca (in mass%) alloys were hot-compressed. Dynamic recrystallization (DRX) occurred locally around the insoluble second-phase particles during hot compression of the as-cast sample. Solute Al segregated around the particles activated basal slip operation through the c/a ratio increase in hcp lattice, which led to the DRX localization.
