The effects of gravity level during directional solidification on the microstructure of hypermonotectic Al-In-Sn alloys

Five hypermonotectic Al-In-Sn compositions were directionally solidified in a Bridgman-type furnace at normal gravity and during aircraft low-gravity maneuvers. The tendency of the Al-30In alloy to form an indium-rich band at the start of unidirectional growth (SUG) made it difficult to study the integration of L sub 2 into the solidification interface. Hypermonotectic compositions closer to monotectic slightly hypermonotectic caused only a partial band on L sub 2 to form at SUG and allowed the study of such variables as gravity, composition, and monotectic dome height on integration of excess L sub 2 into the solid plus L sub 2 interface. It was found that formation of aligned composite structures for the Al-In-Sn system is not only a function of G and R but also of the degree to which the composition varies from monotectic. Most of the aligned fibrous structures formed from hypermonotectic Al-In-Sn had spacings that were of the order of irregular fibrous structures reported for on monotectic Al-In-Sn. The spacings for the large fibers and aligned globules found for ground and low-gravity processed Al-In-18-Sn-22, respectively, were significantly larger than the others measured and were of the order expected for cell spacings under the growth conditions utilized. It was found that the integration into the solidification front of excess L sub 2 in low gravity was a function of the Sn composition of the alloy

Cellular solidification in a monotectic system

Succinonitrile-glycerol, SN-G, transparent organic monotectic alloy is studied with particular attention to cellular growth. The phase diagram is determined, near the monotectic composition, with greater accuracy than previous studies. A solidification interface stability diagram is determined for planar growth. The planar-to-cellular transition is compared to predictions from the Burton, Primm, Schlichter theory. A new technique to determine the solute segregation by Fourier transform infrared spectroscopy is developed. Proposed models that involve the cellular interface for alignment of monotectic second-phase spheres or rods are compared with observations

Tentativi di avvicinamento a due mots-cible a partire da La zia d’america e Il quarantotto: popolo e morale

The main idea of this essay is to read Sciascia in his own words, by removing from his words the timeworn layers of interpretation. Perhaps I am exceeding the ambition that inspired those who made and continue to make their way in the study of the Sicilian writer, yesterday armed with ideology and today with philology. And yet, armed with the words chosen for my reading, ‘people’ and ‘morality’, I tried to be more detached from myself. Rather than being moved by the words of the writer, my 2007 book Le farfalle di Madrid. L’antimonio, i narratori italiani e la guerra civile spagnola (Roma, Bulzoni, 2007; Spanish trans. by M. Manrique and J. Joaquín Blasco Zaragoza, Mariposas de Madrid. Los narradores italianos y la guerra civil española, Prensas Universitarias Zaragoza, 2009) had deployed an army of critical readings and cultural approaches: the second edition of Gli zii di Sicilia (1960), which included L’antimonio, was almost besieged by a ‘pluralistic method’ and, at times, even by deliberate ‘misreadings’. Without regretting the interpretive impetus of youth, which I always regard with admiration, today I try to stand by the people that speaks in Sciascia’s La zia d’America and Il quarantotto, two remarkable stories that are part of Gli zii di Sicilia, because this essential collection, already from its first 1958 edition, was designed to reconnect the Sicilian people with its modern history and even with its genetic background, which carries in itself a silent (but strongly present and active) hope and a clear ‘loyalty to the principles of morality and dignity’
