| 1 | Effect of hot rolling and annealing temperatures on the microstructure and mechanical properties of SP-700 alloy显示文摘The effect of rolling temperature on both two-and single-phase regions and annealing in a temperature range of 700–950°C on the microstructure and mechanical properties of Ti-5 Al-4 V-2 Fe-1 Mo alloy was investigated. The results indicated that the best balance of strength and ductility is obtained by rolling in the two-phase region due to the globularization of the alpha phase and increase in its volume fraction. After rolling in the two-phase region, the ductility of the specimens annealed at 700 to 800°C increased because of the finer size and globularized alpha phase, while the reduction in strength was attributed to a decrease in the alpha phase volume fraction. However, at 950°C, the strength increased and ductility dropped by the formation of acicular alpha phase due to an increase in the phase boundary area. Annealing and aging after rolling in the beta-phase region increased the strength and decreased the ductility, which is attributed to the formation of a secondary alpha phase. A combination of favorable yield strength(1113 MPa) and elongation(13.3%) was obtained through rolling at 850°C followed by annealing at 750°C and aging at 570°C. | Parnia Parvizian Maryam Morakabati Saeed Sadeghpour | 2020 | International Journal of Minerals,Metallurgy and Materials2020，27，3： | 4 |

| 12 | Advances in high carbon dioxide separation performance of poly(ethylene oxide)-based membranes显示文摘Poly(ethylene-oxide)(PEO)-based membranes have attracted much attention recently for CO2 separation because CO2 is highly soluble into PEO and shows high selectivity over other gases such as CH4 and N2.Unfortunately,those membranes are not strong enough mechanically and highly crystalline,which hinders their broader applications for separation membranes.In this review discussions are made,as much in detail as possible,on the strategies to improve gas separation performance of PEO-based membranes.Some of techniques such as synthesis of graft copolymers that contain PEO,cross-linking of polymers and blending with long chains polymers contributed significantly to improvement of membrane.Incorporation of ionic liquids/nanoparticles has also been found effective.However,surface modification of nanoparticles has been done chemically or physically to enhance their compatibility with polymer matrix.As a result of all such efforts,an excellent performance,i.e.,CO2 permeability up to 200 Barrer,CO2/N2 selectivity up to 200 and CO2/CH4 selectivity up to 70,could be achieved.Another method is to introduce functional groups into PEO-based polymers which boosted CO2 permeability up to 200 Barrer with CO2/CH4 selectivity between 40 and 50.The CO2 permeability of PEO-based membranes increases,without much change in selectivity,when the length of ethylene oxide is increased. | Samaneh Bandehali Abdolreza Moghadassi Fahime Parvizian Sayed Mohsen Hosseini Takeshi Matsuura Ezatollah Joudaki | 2020 | Journal of Energy Chemistry2020，29，7： | 0 |
