Twinning of CaMgSi phase in a cast Mg–1.0Ca–0.5Si–0.3Zr alloy
Two types of twins and an orientation domain (orientation twin) were found in CaMgSi particles formed in a Mg–Ca–Si alloy by transmission electron microscopy. The two types of twins were shown to be a (1 0 2) twin with the (1 0 2) plane serving as the twinning plane and a (0 1 1) twin with the (0 1...

| description | Two types of twins and an orientation domain (orientation twin) were found in CaMgSi particles formed in a Mg–Ca–Si alloy by transmission electron microscopy. The two types of twins were shown to be a (1
0
2) twin with the (1
0
2) plane serving as the twinning plane and a (0
1
1) twin with the (0
1
1) plane serving as the twinning plane. In addition to the frequently observed two-fold twin, two different three-fold twins were also observed in the (1
0
2) twinned CaMgSi particles; their crystallographic features are discussed in detail. The boundaries of both the (1
0
2) and (0
1
1) twins were found to be coincident with the twinning plane. The orientation domains were formed by one segment rotating 60° about the [1
0
0] axis relative to the other. The possible formation mechanisms of the twins and orientation domain are discussed based on a crystallographic consideration. |
