| 1 | Strengthening mechanisms in magnesium alloys containing ternary Ⅰ,W and LPSO phases显示文摘This study was aimed at identifying underlying strengthening mechanisms and predicting the yield strength of as-extruded Mg-Zn-Y alloys with varying amounts of yttrium(Y) element. The addition of Y resulted in the formation of ternary I(Mg_3 YZn_6), W(Mg_3 Y_2 Zn_3) and LPSO(Mg_(12) YZn) phases which subsequently reinforced alloys ZM31 + 0.3 Y, ZM31 + 3.2 Y and ZM31 + 6 Y, where the value denoted the amount of Y element(in wt%). Yield strength of the alloys was determined via uniaxial compression testing, and grain size and second-phase particles were characterized using OM and SEM. In-situ high-temperature XRD was performed to determine the coefficient of thermal expansion(CTE), which was derived to be 1.38 × 10^(-5 K^(-1) and 2.35 × 10^(-5) K^(-1) for W and LPSO phases, respectively. The individual strengthening effects in each material were quantified for the first time, including grain refinement, Orowan looping, thermal mismatch, dislocation density, load-bearing, and particle shearing contributions. Grain refinement was one of the major strengthening mechanisms and it was present in all the alloys studied,irrespective of the second-phase particles. Orowan looping and CTE mismatch were the predominant strengthening mechanisms in the ZM31 + 0.3 Y and ZM31 + 3.2 Y alloys containing I and W phases, respectively, while load-bearing and second-phase shearing were the salient mechanisms contributing largely to the superior yield strength of the LPSO-reinforced ZM31 + 6 Y alloy. | N.Tahreen D.F.

| 3 | CODEPOSITION OF ALUMINUM AND SILICON ON PURE MOLYBDENUM SUBSTRATE USING HALIDE ACTIVATED PACK CEMENTATION TREATMENTS显示文摘A multi-component diffusion coating has been developed to protect Mo-based alloys from high temperature environmental attack. Aluminum addition was made during the coating process to improve the oxidation resistance by developing hexagonal Mo(Si, Al)2 through the development of the halide activated pack cementation coating process on pure Mo substrate. The results show that Mo(Si, Al)2 formed as a main phase on the surface and a little amount of Mo5Si3 also formed. The total thickness of coating is tens ofμm at 1373K. During the cyclic oxidation test at high temperature(at about 1323K in air), mullite (3Al2O3.2SiO2) and some SiO2 formed. The addition of Al is beneficial for MoSi2 coating and the Al-doped coating exhibited only a small weight gain and protected the Mo substrate, while the MoSi2 coating without Al suffered a significant weight loss, indicating a loss of volatile MoO3 after cycles. | J.L.

| 12 | 母体特征联合宫颈长度在预测双胎妊娠自发早产中的作用显示文摘Objective: The purpose of this study was to examine the value of combining maternal characteristics and measurement of cervical length at 22 to 24 weeks in the prediction of spontaneous early preterm delivery. Study design: Cervical length was measured by transvaginal sonography at 22 to 24 weeks in 1163 twin pregnancies attending for routine antenatal care. Logistic regression analysis was used to examine the effect of maternal demographic characteristics and cervical length on the risk of spontaneous early preterm delivery. Results: The rate of spontaneous delivery before 32 weeks was 6.5% . The rate of early delivery was inversely related to cervical length,and for a false-positive rate of 10% , the detection rate of early delivery was 65.3% . The respective detection rate for maternal characteristics and obstetric history was 26.4% . Logistic regression analysis demonstrated that the only significant independent predictor of spontaneous early delivery was cervical length. Conclusion: In twins, the prediction of spontaneous early preterm delivery by measurement of cervical length at 22 to 24 weeks is not improved by maternal characteristics. | To M.S. Fonseca E.B.
