“…Theoretical assumptions have been proved by some researchers for a dilute (up to 1 wt.%) [ 11 , 12 , 13 , 14 ] as well as higher Sn contents (5–8 wt.%) [ 15 , 16 , 17 ]. The extruded and hot rolled Mg-0.4Sn-0.7Y alloy sheets investigated by Wang et al [ 12 , 13 ] exhibited high ductility (around 33 and 32%, respectively) which has been attributed to the significant texture weakening and basal texture splitting. Suh et al [ 14 ] showed also that the small addition of Sn (1 wt.%) instead of Zn to Mg-3Al alloy improves its stretch formability due to uniform deformation and activation of the prismatic <a> slip.…”

Microstructure, Texture and Mechanical Properties of Mg-6Sn Alloy Processed by Differential Speed Rolling

et al. 2020

The effect of shear deformation introduced by differential speed rolling (DSR) on the microstructure, texture and mechanical properties of Mg-6Sn alloy was investigated. Mg-6Sn sheets were obtained by DSR at speed ratio between upper and lower rolls of R = 1, 1.25, 2 and 3 (R = 1 refers to symmetric rolling). The microstructural and textural changes were investigated by electron backscattered diffraction (EBSD) and XRD, while the mechanical performance was evaluated based on tensile tests and calculated Lankford parameters. DSR resulted in the pronounced grain refinement of Mg-6Sn sheets and spreading of basal texture as compared to conventionally rolled one. The average grain size and basal texture intensity gradually decreased with increasing speed ratio. The basal poles splitting to transverse direction (TD) or rolling direction (RD) was observed for all Mg-6Sn sheets. For the as-rolled sheets, YS and UTS increased with increasing speed ratio, but a significant anisotropy of strength and ductility between RD and TD has been observed. After annealing at 300 °C, Mg-6Sn sheets became more homogeneous, and the elongation to failure was increased with higher speed ratios. Moreover, the annealed Mg-6Sn sheets were characterized by a very low normal anisotropy (0.91–1.16), which is normally not achieved for the most common Mg-Al-Zn alloys.

“…The addition of Y to lean Mg–Sn alloys influences the mechanical properties of as-extruded sheets at RT positively, especially the elongation to break showed marked improvement. Investigations on Mg-0.3Sn-0.7Y [ 101 ] and Mg-0.5Sn-0.3Mn-0.3Y [ 102 ] alloys attributed this to a decreased grain size, favorable texture and the increased activity of non-basal slip when compared to the alloys without Y. Subsequent work confirmed this also for rolled and annealed sheets made from Mg-0.3Sn-0.7Y [ 103 ].…”

Lean Wrought Magnesium Alloys

et al. 2021

View full text Add to dashboard Cite

Lean magnesium alloys are considered attractive candidates for easy and economical hot forming. Such wrought alloys, defined here as materials with a maximum alloying content of one atomic or two weight percent, are known to achieve attractive mechanical properties despite their low alloy content. The good mechanical properties and the considerable hardening potential, combined with the ease of processing, make them attractive for manufacturers and users alike. This results in potential uses in a wide range of applications, from rolled or extruded components to temporary biomedical implants. The characteristic behavior of these alloys and the optimal use of suitable alloying elements are discussed and illustrated exemplarily.

“…Moreover, the extruded Mg-Sn-based alloys with high Sn content commonly have sub-microscale and microscale Mg 2 Sn particles co-existing at the grain boundary in the form of network, which prevents further performance improvement (Cheng et al, 2010). Many previous reports have verified that decreasing the alloying element contents of Mg alloys could efficiently reduce the thermally stable phase contents and modify the morphologies of the strengthening precipitates (Hofstetter et al, 2015;Pan et al, 2018;Wang et al, 2018;Hu et al, 2019), thus improving the extrudability and ductility. Accordingly, studies have recently been concentrated on micro-alloyed systems with low content of Sn in order to reduce the cost of products (Chai et al, 2019a).…”

Microstructural Characteristics and Mechanical Properties of a Novel Extruded Dilute Mg–Sn–Mn–Ca Alloy

et al. 2019

View full text Add to dashboard Cite

A novel dilute Mg-Sn-Mn-Ca (TMX) alloy system was developed and subjected to extrusion with a relatively high extrusion ratio of 36. The grain structure, nanoscale precipitates, texture, and tensile properties of the extruded dilute alloy were investigated. The results indicated that complete dynamic recrystallization (DRX) together with some nanoscale and/or sub-microscale Mg 2 Sn and Mg 2 Ca precipitates could be obtained after extrusion. The tensile yield strength, ultimate tensile strength and elongation of the extruded dilute alloy were 213 and 266 MPa, and 21%, respectively. The correlation between microstructural characteristics and properties was also discussed.
