Influence of Mn content on mechanical properties and fatigue behavior of extruded Mg alloys

Effect of Aluminium Content on the Tensile Properties of Mg-Al-Zn Alloys

“…The result shows that AZ61 exhibited higher tensile strength and better work hardening as compared to that of the AZ31, which caused by the grain size reduction and Mg 17 Al 12 precipitation. Khan et al (2006) and Ryu et al (2000) have reported that the higher tensile strength was due to the effects of smaller grain size and higher density of Work hardening rate for AZ31 and AZ61 were clearly shows in Figure 5. It is noted that the work hardening rate for AZ61 was greater compared to that of AZ31 due to the existence of precipitation and fi ner grain size of alloy.…”

“…On the other hand, the existence of twinning in a material would also contribute to higher fl ow stress and better work hardening (Yablinsky et al 2006). However, in most magnesium alloy series, fi ner grain size and Mg 17 Al 12 precipitation have more infl uenced to improve the strength, work hardening and ductility despite of the smaller grain size would be suppression the twinning (Barnett 2007;Khan et al 2006). precipitation (Khan et al 2006, Ryu et al 2000.…”

Microstructural changes in an extruded Mg Zn Y alloy reinforced by quasicrystalline I-phase by small additions of calcium, manganese and cerium-rich mischmetal

“…Moreover, both elements contribute to randomize the basal texture [22]. The complete insolubility of manganese produces a fine dispersion of manganese particles in the magnesium matrix which strengthens the alloy through the refining of the grain size in magnesium alloys [23,24].…”

In vitro and In vivo Degradation Evaluation of Mg-Based Alloys for Biomedical Applications

“…The mechanical properties, such as tensile strength and yield strength, can be improved effectively [17][18][19]. On the other hand, Mn is used commonly as an alloying element to remove impurities in alloys [20].…”
