Study on the Effect of Base Pressure on Magnetron Sputtering Discharge Plasma by Optical Emission Spectroscopy

引用

Plasma Science and Technology 2010年第1期12卷 35-40页

作者： S.YUGESWARAN k.suresh V.SELVARAJAN Plasma Physics Laboratory Department of Physics Bharathiar University

Argon plasma was generated by DC magnetron sputtering discharge at a constant input power and sputtering pressure. The emission spectra of the argon plasma, in a region of 300 nm to 800 nm, were recorded with three different base pressures （4×10^-4 Pa, 13×10^-4 Pa and 26×10^-4 Pa）. From the spectra, the Boltzmann temperature （TB） was calculated by using the atomic Boltzmann plot method. The intensity ratio of N and N2 lines provided the information on the changes in the degree of dissociation of nitrogen molecules. The obtained results showed that with the increase in base pressure the dissociation of N2 increased and the Boltzmann temperature （TB） decreased.

Microstructure and mechanical properties of as-cast Mg-Sn-Ca alloys and effect of alloying elements

引用

Transactions of Nonferrous Metals Society of China 2013年第12期23卷 3604-3610页

作者： k.suresh k.P.RAO Y.V.R.k.PRASAD N.HORT k.U.kAINER Department of Mechanical and Biomedical Engineering City University of Hong Kong Consultant *** No. 2/B Vinayaka Nagar Helmholtz-Zentrum Geesthacht Institute of Materials Research Magnesium Innovation Centre

The effect of Sn, Ca, Al, Si and Zn addition on the compressive strength of cast Mg-Sn-Ca （TX） alloys was studied in the temperature range of 25-250 °C and correlated with the microstructure. The Sn to Ca mass ratio up to 2.5 contributes to the formation of Mg2Ca phase at the grain boundaries and CaMgSn in the matrix, while a ratio of 3 gives only CaMgSn phase mostly in the matrix. While the compressive strength decreases with the increase in temperature, for Sn/Ca up to 2.5, a plateau occurs in 100-175 °C, which is attributed to the strengthening by Mg2Ca. However, for ratio of 3, the strength is lower and decreases more gradually. Mg-3Sn-2Ca （TX32） has the highest strength and the addition of 0.4%Al increases its strength but simultaneous addition of Si lowers the strength. Likewise, the addition of Zn improves its strength but simultaneous addition of Al slightly decreases the strength. The results are correlated with the types of intermetallic phases that form in various alloys.

由于具有很大的吸附容量,多孔炭材料是优良的吸附剂。笔者试图比较海枣核分别经CO2活化和磷酸活化所制活性炭的结构和吸附性能。活化过程和工艺条件对炭的物理化学性质影响较大,根据文献报道的结果选取了优化的工艺参数。基于氮气吸附等温线、SEM、FT-IR等分析结果,评估了活性炭的结构特征,吸附性能则由亚甲蓝吸附值表示。CO2活化得到了微孔活性炭,产率为44%、BET比表面积是666 m2·g-1;磷酸活化得到了产率为14.8%的中孔活性炭,BET比表面积为725 m2·g-1。CO2活化活性炭的平均孔径是1.51 nm,磷酸活化活性炭的则为2.91 nm。活性炭的亚甲蓝吸附等温线分别用Langmuir等温线和Freundlich等温线进行了验证,在优化工艺条件下制备的CO2活化炭和磷酸活化炭的亚甲蓝w单分子吸附容量分别为110 mg·g-1和345 mg·g-1。然而,磷酸活化产生的亚甲蓝吸附值最高达455 mg·g-1。

Hot forging of Mg-4Al-2Ba-2Ca(ABa X422) alloy and validation of processing map

引用

Transactions of Nonferrous Metals Society of China 2018年第8期28卷 1495-1503页

作者： k.suresh k.P.RAO Y.V.R.k.PRASAD N.HORT H.DIERINGA Department of mechanical and Biomedical Engineering City Uiliversity of Hong Kong Tat Chee Avenue Kowloon Hoilg Koilg China *** No. 2/B vinayaka Nagar Hebbal Bengalum 560024 India Helmholtz-zentrum Geesthacht institute of Materials ResearchMagnesium innovation Centre Max-Planck-StraBe 1 Geesthacht 21502 Germany

A cup-shaped component of Mg-4 Al-2 Ba-2 Ca（ABa X422） alloy was forged in the temperature range of 300-500 °C and at speeds in the range of 0.01-10 mm/s with a view to validate the processing map and study the microstructural development. The process was simulated through finite-element method to estimate the local and average strain rate ranges in the forging envelope. The processing map exhibited two domains in the following ranges：（1） 300-390 °C and 0.0003-0.001 s^-1, and（2） 400-500 °C and 0.0003-0.3 s^-1 and both represented dynamic recrystallization（DRX）. The map revealed a wide flow instability regime at higher strain rates and temperatures lower than 400 °C, in which flow localization occurred. Forgings produced under conditions of the above two domains were sound and symmetrical, and had finer grain sizes when being forged in the first domain. However, when being forged in the flow instability regimes, the alloy fractured before the final shape was reached. The experimental load-stroke curves for the conditions within the domains correlated well with the simulated ones, whereas the curves obtained in the instability regime were uneven.
