Microstructure and mechanical properties of conventional cast and rheocast Mg–Sn based alloys

Effect of Li on microstructure, mechanical properties and fracture mechanism of as-cast Mg–5Sn alloy

“…The fracture surface of Mg-5Sn alloy shown in Fig. 7d consists of dimples, second cracks, cleavage steps, tearing ridges, and cleavage plane [37][38][39]. The appearances of cleavage steps and river pattern around the dimples suggest that the mechanism of mixture of cleavage fracture and dimple fracture [36].…”

Electrical and thermal conductivity in Mg–5Sn Alloy at different aging status

“…Therefore, magnesium alloys are attractive candidates for heat dissipation materials in LED etc., compared with aluminum alloys. The Mg-Sn alloys, known as a typical precipitation hardening system [3], have great potential applications in heat dissipation materials at elevated temperatures (b423 K) due to the Mg 2 Sn phase, which has a high melting temperature of 1043 K [4][5][6]. For Mg-Sn alloys, most researchers have given more attention to the improvement of aging hardening on the performance of the alloys [7][8][9][10].…”

Nanoscale precipitates strengthened lanthanum-bearing Mg-3Sn-1Mn alloys through continuous rheo-rolling

“…These secondary strengthening phases, formed through microalloying, can assist in retaining a high dislocation density in the alloy by promoting the multiplication of dislocations and by pinning them, thereby improving the mechanical properties of Mg-alloys 3 4 . Previous research has shown that the addition of Si or Sn in magnesium alloys led to the formation of thermally stable and high-hardness Mg 2 Si or Mg 2 Sn phases, and thus improved the mechanical properties of Mg alloys at room and high temperatures 5 6 7 8 . We selected Sn instead of Si as one of the alloying elements considering the advantages of Mg 2 Sn phase and disadvantages of Mg 2 Si phase.…”
