The mechanical properties and microstructure were investigated under different Zn content heat treatment conditions in a Mg–Zn–Y–Gd cast alloy. A part of the long period stacking order (LPSO) phases transformed to W-Mg3Zn3RE2 with an increase from 0.9 at.% 1.8 at.%, ultimate tensile strength (UTS) increased 229 MPa 248 MPa. With solution at 480°C, LPSO phase sharply decreased Mg-1.8Zn-0.8Y-0.8Gd alloy, whereas this change was not significantly observed Mg–0.9Zn–0.8Y–0.8Gd After treatment,...
Recently, multi-pass caliber rolling has been shown to be effective for Mg alloys. This study investigated the effect of subsequent annealing on mechanical properties a caliber-rolled AZ31 alloy modulate strength-ductility relationship. gave rise different trends in depending temperature regime. Low-temperature (T ≤ 473 K) exhibited typical trade-off relationship, where an increase resulted increased ductility but decreased strength and hardness. Such heat treatment did not degrade high...
Composite materials for vehicle parts require lightweight, high strength and good impact properties. In this study, the optimized manufacturing conditions of epoxy foam (EF) were investigated to improving mechanical performance carbon fiber reinforced plastic (CFRP)/EF/CFRP sandwich composites such as impact, flexural property. The optimal curing temperature was found be 60 °C, by measuring reaction rate, volume increase density, cell size, glass transition temperature, specific compressive...
This research aims to explore the possibility of a high-strength Mg alloy with low RE content. The Sm element was added Mg-6Zn-0.5Zr-3Nd alloy. Corresponding microstructures and performance evolution were systemically investigated, strengthening mechanisms tried quantified. It indicated addition not only enhanced precipitation process but also changed precipitates. Mg-Zn phases disappeared original Nd3Zn11 replaced by (Nd,Sm)3Zn11 after addition. extrusion further process. Both micron-scale...
This study investigated the microstructure and mechanical properties of Mg-1Gd-1Y-1Zn (at.%) alloys containing designed amounts Ce or La. The Mg<sub>5</sub>(Gd,Zn) phase formed in as-cast Mg-Gd-Y-Zn-Ce/La disappeared after a homogenization treatment at 500°C for 24 h. addition La resulted formation Ce(Mg,Zn)<sub>12</sub> La(Mg,Zn)<sub>12</sub> phases, respectively. Except that, had no significant effect on morphology, volume fraction, type long-period...
The microstructures of Mg 96 Y 2 Zn , 1 Co Ni and 0.5 (at.%) alloys were investigated by XRD, SEM/EDS, TEM. α ‐Mg matrix, the long‐period stacking ordered (LPSO) phase, bright compounds observed in as‐cast alloys. ability to form LPSO phase with is weaker than that Zn, but it can produce some new intermetallic compounds. effect on content was opposite Co. After replacing partial Ni, increase more obvious or alone replace Zn. atoms Mg‐Y‐TM be ranked as follows: Co‐Ni > From point‐of‐view...
The multi-pass caliber rolling (MPCR) of Mg alloy has attracted much attention due to its engineering and manufacturing advantages. MPCR process induces a unique microhardness variation, which only been predicted using finite element analysis thus far. This study employed machine learning as an alternative method prediction for the first time. For this purpose, two machine-learning approaches were evaluated: artificial neural network (ANN) approach that aided by generative adversarial...
Multi-pass caliber rolling has proven its vast potential for ultrafine-scale grain refinement and mass production of various metals. Nevertheless, the studies related to Mg alloys have primarily focused only on a few commercial materials, such as AZ31 ZK60 alloys. This is first study investigate caliber-rolled Mg–1Sn (TM10) Mg–1Sn–1Mn (TM11) Specifically, this work aims elucidate microstructural characteristics these alloys, including refinement, recrystallization, texture development. Such...
