    Notes: The addition of strontium to Mg-Al based alloys offers good creep resistance to meet thematerial requirements for automotive applications. The composition, microstructure and mechanicalproperties of Mg-Al-Sr alloys are discussed in this paper. The effects of alloy elements such as Ca, Tiand Mn in Mg-Al-Sr alloy are summarized. Technologies for preparation of Mg-Sr master alloy weredeveloped, including mixture method and vacuum thermal reduction method which may also be usedfor preparation of Mg-Al-Sr alloys

    Preparation of Mg-Sr Alloys Using Vacuum Reduction: A Thermodynamics Approach (2007)

    Notes: At the present Mg-Sr alloy is usually produced by alloy mixing process ormelt-leaching-reduction process which has low productivity. A new process has been developedtermed “Preparation Mg-Sr alloys using vacuum thermal reduction”. The principle and procedure ofthe new process were discussed in this paper. The reduction thermodynamics was analyzed, includingestablishing the oxygen potential diagram of Sr, Mg, Si and Al, determination of main reactions, andevaluation of Gibbs free energy in vacuum. The results showed that Mg-Sr alloys can be obtained bysynchronous reduction of SrO and MgO from a mixture of MgO, SrO, Si, CaO. The equipment,reduction temperature and vacuum for the new process have been also discussed

    Determination of Sr Content in Mg-Sr Alloys Using Faas (2007)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: The Air-acetylene Flame Atomic Absorption Spectrometry (FAAS) was used to measureSr content in Mg-Sr Alloys. The experiment conditions including acetylene flow rate, measurementheight, flame wavelength were studied and the disturbing factors were discussed. It was found that, asdissolution agent of alloys and LaCl3 as the deionization agent and flame wavelength being 460.7nm,the detection limits is 1.16mg/L and the relative standard deviations is less than 0.3% and the recoveryrates of Sr is more than 95%. The advantages of this method were summarized as: high sensitivity andprecision, low chemistry disruption, good selectivity, good recurrence characteristics of themeasuring conditions. The method is suitable for the control analysis and sample-system analysis ofdetermination Sr content in the Mg-Sr Master Alloys
