Microstructure and mechanical properties of Mg–Zn–Y alloy containing LPSO phase and I-phase
Materials Research Express, 2017 Microstructure and mechanical properties of Mg–Zn–Y alloy including LPSO phase and I-phase was investigated. Transmission electron microscopy, x-ray diffraction analysis and differential scanning calorimeter analysis reveal that the LPSO (long period stacking ordered structure) phase and I-phase can co-exist within the α-Mg matrix.

Strengthening of Mg-based long-period stacking ordered (LPSO) phase with deformation kink bands [PDF]
The mechanical properties of the Mg-based LPSO-phase are expected to be strongly affected by the microstructure due to its anisotropic crystal structure. However, the fine details have not been sufficiently understood yet.

High-Temperature Mechanical Behavior of Extruded Mg-Y-Zn Alloy Containing LPSO Phases
Metallurgical and Materials Transactions A, 2013 The high-temperature mechanical behavior of extruded Mg97-3x Y2x Zn x (at. pct) alloys is evaluated from 473 K to 673 K (200 C to 400 C). The microstructure of the extruded alloys is characterized by Long Period Stacking Ordered structure (LPSO) elongated particles within the magnesium matrix.

Reverse tension/compression asymmetry of a Mg–Y–Zn alloys containing LPSO phases
Materials Science and Engineering: A, 2015 © 2015 Elsevier B.V. Room temperature mechanical behavior of extruded Mg-Y-Zn alloys with varying fractions of LPSO phase was studied in tension and compression along the extrusion direction. The microstructure is characterised by elongated LPSO fibers along the extrusion direction within the magnesium matrix.

The evolution of LPSO phase and its influence on grain size during cooling free forging
Materials Research Express, 2021 In this paper, the deformation behavior of the LPSO phase of Mg-Gd-Y-Zn-Zr and its influence on the grain size are studied during the cooling free forging deformation. Studies have shown that cooling free forging can refine different forms of LPSO phases.
