Novel AZ91D Mg alloy/fly-ash cenospheres (AZ91D/FAC) composites were fabricated by melt stir technique. The thermodynamic analyses of the interfacial reactions, the microstructure observation, and the phase analyses of the AZ91D/FAC composites were investigated. The results showed that the cenospheres were almost filled with Mg alloy matrix. In-situ MgO and Mg2Si phases were formed in Mg alloy matrix and near the interfaces between the cenospheres and Mg alloy matrix. Through the thermodynamic calculation, it can be found that the standard free enthalpy changes of these interfacial reactions are all negative at the temperature of Mg alloy melt preparation in this work, and these reactions can occur.

AbstractIn this essay, I focus on the initial reaction of the then leadership of the Academy of Management (AOM) to President Trump’s travel ban issued in January 2017. By viewing the travel ban in purely administrative terms, AOM leadership framed it as an example of “political speech”, on which they were organizationally barred to take a public stand. I subject this view to critical assessment, arguing that the travel ban had a distinct moral character, which was antithetical to scholarly values. Τhe travel ban, I suggest, should be viewed as a non-prototypical case of political speech, which required AOM leadership to flexibly adapt existing rules in situ: to imaginatively frame the travel ban in order to undertake responsible action. Accordingly, the early 2017 AOM rules about political speech should be seen not as recipes-for-action but as reminders-for-action, thus allowing an imaginative reframing. Finally, exploring the notion of moral imagination, I distinguish between “disclosive” and “incremental” moral imagination and responsibility, and suggest that AOM leadership engaged mainly in the latter.

ABSTRACTThe initial stages of interfacial reactions of ultrahigh vacuum (UHV) deposited Ti thin films on silicon have been studied by in-situ reflected high energy electron diffraction (RHEED) and transmission electron microscopy (TEM).An amorphous interlayer was found to form during the deposition of the first 1.7-nm-thick Ti layer. In samples annealed at 450 °C for 30–120 min, Ti5Si3, located at the Ti/a-interlayer interface, was identified to be the first nucleated phase. Ti5Si3, Ti5Si4, TiSi and C49-TiSi2 were observed in samples annealed at 475 °C for 30 and 60 min as well as at 500 °C for 10 and 20 min. Fundamental issues in silicide formation are discussed in light of the discovery of the formation of the amorphous interlayer and as many as four different silicide phases in the initial stages of interfacial reactions of UHV deposited Ti thin films on silicon.
