8Effect of Gas Bubbling Filtration Treatment on Microporosity Variation in A356 Aluminium Alloy显示文摘In the present study,the contribution of the gas bubbling filtration(GBF) process to the microporosity variation,microstructural characteristics and tensile properties of A356 aluminium alloy was investigated.The test specimens were fabricated through gravity casting in terms of the process variables:the degassing time,the impeller rotation and the aperture size of gas inlet hole.The density measurement and scanning electron microscope fractography analyses were conducted to evaluate the variation of the volumetric porosity and fractographic porosity with the GBF process,respectively.The fractographic porosity of the specimens can be minimised under specific GBF conditions in terms of the buoyant velocity and the absorbing capacity of gas bubbles,the inclusion of oxide films,whereas the volumetric porosity can be wholly reduced on the lapse of degassing time.The ultimate tensile strength(UTS) and elongation at optimal conditions were improved to approximately 30 MPa and 1.5%compared with no GBF treatment.Even though an extension of the degassing time and/or excessive stirring action of the melt may induce the inclusion of bifilm oxides and the increase of fractographic porosity,the tensile properties of over-treated specimens were maintained to a level which is similar to those that did not undergo GBF treatment due to the grain refinement accompanying with the GBF process.In addition,the defect susceptibility of UTS and elongation to microporosity variation could be remarkably improved at an optimal GBF condition.Choongdo Lee Taeil So Kwangseon Shin 2016Acta Metallurgica Sinica(English Letters)2016,29,7:0
9Effects of stress loading mode on microstructures and properties of Mg-9Gd-2Nd-0.5Zr alloy treated by creep aging显示文摘Creep aging forming(CAF) is a potential process used to manufacture large integral components of magnesium(Mg) alloys. The selected stress plays a crucial role in creep aging processes but the mechanism by which stress loading method affects creep aging of Mg alloys is still unclear. In this paper, the microstructural evolution of precipitated phases and precipitation-free zones(PFZ) at grain boundaries with different stress loading modes(unstressed, unidirectional tensile stress, and cyclic stress) at 250 ℃ were investigated along with changes in mechanical properties. The results showed that the addition of stress during aging effectively promoted the precipitation of precipitated phases, while unaffecting grain size. Unidirectional tensile stress caused directional growth of β phase([1010]), as well as rotation of weave towards the basal plane texture, resulting in namely stress orientation effect. Solute atoms diffused in the direction of tensile stress while vacancies moved perpendicular to the direction of tensile stress, resulting in PFZ at grain boundaries(157.06 nm). By contrast, cyclic stresses led to the growth of β phase in three directions([1010], [1100] and [0110]). The solute atoms and vacancies were uniformly distributed in the Mg matrix instead of directional diffusion, effectively reducing the width of PFZ(112.39 nm) at the grain boundary. These features significantly improved the mechanical properties of alloy specimens after cyclic stress creep aging when compared to unidirectional stress creep aging, with yield strength(YS), ultimate tensile strength(UTS), and elongation(EL) enhanced from 171.6 MPa, 305.5 MPa, and 4.4%to 174.8 MPa, 326.3 MPa, and 6.9%, respectively.Simin Shen Yongpeng Zhuang Ming Li Hongxia Wang Lifei Wang Weili Cheng Hang Li Hua Hou Kwangseon Shin 2023Journal of Magnesium and Alloys2023,11,11:0
