Tailoring the microstructure and suppressing the β-AlFeSi intermetallic formation in 319 aluminum alloy through spray forming
Contributors: Lucas Otani
... Iron has very low solubility in aluminum, leading to the formation of Fe-rich intermetallic phases, such as β-AlFeSi. This phase forms with a platelet-like morphology that is detrimental to the mechanical properties of the alloy. It is well known that by applying high cooling rates or by adding manganese to the alloy it is possible to stabilize the α-AlFeSi or α-Al(Fe,Mn)Si intermetallic phase instead of the more detrimental β-AlFeSi. Spray forming is an advanced casting process that has been described as a potential technique to suppress β-AlFeSi formation. This work investigated the effect of different processing parameters on the microstructure evolution of spray-formed aluminum 319 alloy, mainly regarding the formation of α and β intermetallic phases. Results showed that the suppression of the β-AlFeSi strongly depends on the processing conditions and can be explained by the solidification mechanism prevailing in spray forming.

... Abstract of associated article: We examine the largest cost component in offshore development projects, rig rates. High rig rates in recent years have restricted development of new oil and gas fields, as well as IOR projects and thus increased the cost for importing countries. Thus, it is important to understand developments in rig rates. Using econometric analysis, we examine the effects on jackup rig rates from gas and oil prices, rig capacity utilisation, contract length and lead time, and rig-specific characteristics like drilling depth capacities and rig classification. Having access to a unique data set from the Gulf of Mexico (GoM), containing contract information, we are able to estimate how contract parameters crucial to the relative bargaining power between rig owners and oil and gas companies affect rig rates. We find that increasing lead times and contract lengths enhance the bargaining power of the rig companies and are likely to be associated with higher rates for new contracts. Further, we find that gas prices are more important for jackup rig rates in the GoM area than oil prices — ten percent increase in gas prices leads to nine percent increase in rig rates in the long run, according to our results.
