چکیده
The influence of alloying elements and heat treatment on the microstructure mechanical behaviors extruded Mg–Gd–Nd ternary alloys was investigated in this study. grain sizes dramatically decreased after extrusion, particles which distributed Mg matrix had great effect size. from 26 to 5 μm with content increasing. test results show that both Gd Nd positive hardness, yield strength Young's modulus. ultimate tensile (UTS) enhanced by content, content. elongation lower higher elements. Those were aged for 200 h °C. moduli ageing treatment. Combined study, part reinforcement identified as Mg5(Gd/Nd) dissolved matrix. element obviously has solubility alloys.

Synthesis and mechanical properties of nanostructured Mg-Al-Nd alloys
In this work, nanostructured Mg-Al-Nd alloys were successfully fabricated using mechanical alloying method. Phase structures of the milled powders and the extruded rods were examined using X-ray diffraction (XRD) and the microstructures were observed using a transmission electron microscope (TEM). The element distributions were also examined by an energy dispersive spectroscopy (EDS) system. Th...
متن کاملAchieving High Strength and Good Ductility in As-Extruded Mg–Gd–Y–Zn Alloys by Ce Micro-Alloying
In this study, the effect of Ce additions on microstructure evolution of Mg-7Gd-3.5Y-0.3Zn (wt %) alloys during the casting, homogenization, aging and extrusion processing are investigated, and novel mechanical properties are also obtained. The results show that Ce addition promotes the formation of long period stacking ordered (LPSO) phases in the as-cast Mg-Gd-Y-Zn-Ce alloys. A high content o...
متن کاملSelf-patterning Gd nano-fibers in Mg-Gd alloys
Manipulating the shape and distribution of strengthening units, e.g. particles, fibers, and precipitates, in a bulk metal, has been a widely applied strategy of tailoring their mechanical properties. Here, we report self-assembled patterns of Gd nano-fibers in Mg-Gd alloys for the purpose of improving their strength and deformability. 1-nm Gd nano-fibers, with a 〈c〉-rod shape, are formed and he...
متن کاملIn-situ deformation characterization of Nd-containing Mg alloys
An in-situ characterization technique combining mechanical testing inside a scanning electron microscope (SEM) with electron backscatter diffraction (EBSD) analysis was employed to study the tensile deformation behavior of Nd-containing Mg alloys over the temperature range of 50-250°C. EBSD data were collected before and after the experiments. The active slip and twinning systems were identifi ...
متن کاملTailoring microstructure of Mg–Zn–Y alloys with quasicrystal and related phases for high mechanical strength
The occurrence of a stable icosahedral (i-) phase, which is quasicrystalline with an icosahedral (fivefold) symmetry, on the equilibrium phase diagram of Mg-Zn-RE (RE = Y, Gd, Tb, Dy, Ho or Er) alloys opened up an interesting possibility of developing a new series of magnesium alloys for structural applications. Alloys based on the i-phase have been studied for the past 14 years. Ultra-high str...
