摘要：
The deformation behavior of the coherent beta'" phase in a Mg-Nd alloy and beta' phase in a Mg-Y alloy were determined by examining the aged microstructures both before and after deformation using high angle annular dark field scanning transmission electron microscopy. Both phases were sheared by dislocations with < a > basal slip in Mg-Nd and basal < a > and non-basal < c+a > or < a > slip in Mg-Y. (C) 2018 Elsevier B.V. All rights
