The microstructure, tensile properties, and creep behavior of Mg–Zn alloys containing 0–4.4wt.% Zn

Three kinds of atmospheres (air, highly-pure Ar and ultra highly-pure Ar gas) with different oxygen partial pressures were applied to investigate the tensile properties and creep behavior of SiC fibers such as Hi-NicalonTM and TyrannoTM-SA. These fibers were annealed and crept at elevated temperatures ranging from1273-1773 K in such environments. After annealing at 1773 K, the room temperature tensile strengths of SiC-based fibers decreased with decreasing the oxygen partial pressure and the near stoichiometric fiber TyrannoTM-SA shows excellent strength retention. At temperatures above the 1573 K, the creep resistance of SiC fibers evaluated by bending stress relaxation (BSR) method under high oxygen partial pressure was lower than that of in low oxygen partial pressure. The microstructural features on these fibers were examined by scanning electron microscopy (SEM) and X-ray diffraction (XRD).

The microstructure, mechanical properties and creep behavior of Mg-Gd-Y-Zr alloys at different temperatures and stresses have been investigated. Results show that the tensile properties and creep resistance at T6 condition is much higher than that at as-cast condition. The creep resistance of Mg-Gd-Y-Zr alloy at 250°C/80MPa is markedly better than that at 300°C/50MPa, indicating that temperature makes more effects on the creep resistance than the stress.

This study investigated the microstructure and tensile properties of three indirectly extruded Mg-Sn-Al-Zn alloys: Mg-11Sn-1Al-1Zn (TAZ1111), Mg-8Sn-4Al-1Zn (TAZ841), and Mg-8Sn-1Al-4Zn (TAZ814). The investigation results revealed that in all the alloys, Mg2Sn particles formed during solidification were not fully dissolved by homogenization treatment. These undissolved particles enhanced the dynamic recrystallization behavior through a particle-stimulated nucleation phenomenon. As a result, all the extruded alloys exhibited a fully dynamically recrystallized microstructure. The tensile yield strength (TYS) of the extruded alloys was in the following order: TAZ1111 > TAZ841 > TAZ814. In contrast, the elongation of the alloys was in the opposite order: TAZ814 > TAZ841 > TAZ1111. The highest TYS of the TAZ1111 alloy was attributed mainly to the smaller grain size and more abundant Mg2Sn precipitates resulting from a higher Sn content. However, the ultimate tensile strengths of all the extruded alloys were nearly the same because the Al or Zn atoms dissolved in the TAZ841 and TAZ814 alloys improved the strain hardening rate during plastic deformation.
