High-resolution electron microscopy observations of continuous precipitates with Pitsch-Schrader orientation
1Department of Physics and Key Laboratory of Acoustic and Photonic Materials and Devices of Ministry of Education, Wuhan University, Wuhan 430072, China.
Abstract:
High-resolution electron microscopy was applied to analyze the continuous precipitated particles of the gamma-Mg(17)Al(12) phase with Pitsch-Schrader OR in the heat-treated AZ91 alloy at 473 K for 8 h. The existence of a continuous precipitated particle with the Pitsch-Schrader OR including the selection of the habit plane and the growth direction in Mg-Al system is rationalized by the constrained coincidence site lattice/constrained complete pattern shift lattice (CCSL/CDSCL) model and the O-lattice theory.
