Abstract Scope |
LPSO phase is known to contribute to increase in both of strength and ductility of Mg alloys. As a deformation mode in it, kink-band formation is recently focused. However, its formation criteria have not yet been clarified. According to the study on the LPSO phase, its unique crystal structure which is constructed by the alternative stacking of soft and hard layers, called mille-feuille structure, are supposed as plausible factors to govern the formation of deformation kink bands. To confirm these assumptions, we examined the deformation behavior of several directionally solidified Mg-based two-phase eutectic alloy with lamellar microstructure as a model material, such as Mg/Mg17Al12, and confirmed the formation of kink-bands as expected. The details on this is discussed in the presentation. |
