Understanding the interaction of extension twinning and basal-plate precipitates in Mg-9Al using precession electron diffraction
Precession electron diffraction is used to characterize the interaction between {10 1¯ 2}
tensile twins and basal plate-like precipitates in a post-deformed, precipitate-dispersed Mg-
9Al micropillar. We observed a heterogeneous distribution of precipitates in the micropillar
sample, which enabled the study of the different stages involved in twin-precipitate
interactions. We show that twin nucleation was promoted, taking place on the surface, as
well as from the interior of the micropillar. Twin tip propagation and twin growth were …
