Interpretation of Crystallographic Morphologies of Precipitates in Mg Alloys with a Secondary CCSL Model

Abstract:

This work presents a secondary CCSL model to interpret newly observed orientation relationships of fcc Mg₂Sn precipitates and bcc Mg₃₂(Al, Zn)₄₉ precipitates with respect to Mg matrix. The morphologies of these precipitates are characterized with a common feature of well defined facets. The orientations of these facets have been interpreted with the secondary CCSL model.
