N2 - Magnesium alloy with Long-Period Stacking Ordered Structure (LPSO) and α-Mg (ordinary HCP structure) phase is expected for a new structural material due to its excellent mechanical properties. Its materials strengthening arises from the kink band formation in LPSO phase and the grain refinement of α-Mg phase in the vicinity of LPSO phase because of recrystallization.

26/7/2020· The structure of metals explains their high melting and boiling points and their conductivity. The properties of a metal can be modified by mixing it with another substance to form an alloy. A
It is consequently used for grain structure control in all commercial A1-Li base alloys. It is,well established that the cubic (LIZ) A4Zr response of the lithium free alloy is similar to the 8090 alloy of similar copper and magnesium content. The magnitude
The structure, composition and morphology of a radio-frequency (RF) magnetron sputter-deposited dense nano-hydroxyapatite (HA) coating that was deposited on the surface of an AZ31 magnesium alloy were characterized using AFM, SEM, EDX and XRD. The
An increasing nuer of alloys, particularly in the aluminum-zinc-magnesium family, use zirconium additions to increase the recrystallization temperature and to control the grain structure in wrought products. Zirconium additions leave this family of alloys less
The average grain size of Mg-1%Al alloy is 3 097 µm. When the amount of added Al increases to 5%, the average grain size decreases dramatically to 151 µm. Further addition of Al to 9% makes the grain size decrease slowly to 111 µm. These results are[9].

As a rule, the lower alloy content grades require anodizing to reveal the grain structure with cross-polarized light. The more highly alloyed grades can be etched successfully with either Keller’s reagent, the Graft-Sargent reagent, aqueous 10% phosphoric acid (50C) or a mix of 2g NaOH, 5g NaF and 93ml water (immerse 2-3 minutes).

The paper presents the technological aspect of the process of casting, crushing and plastic consolidation of semi-finished products from magnesium alloy. The aim of this study was to produce by the rapid solidifiion process a magnesium alloy from the MgAl9Zn1 family in the form of ribbons with ultrafine grain structure.
MAD and ECAP enhanced alloy biocompatibility in all in vitro tests, while the effect of RS was less significant. In summary, the results obtained demonstrate that not only do the deformation methods employed improve the mechanical properties of alloy WE43, but they also increase its corrosion resistance and biocompatibility in vitro.
