There is a widespread interest in understanding the properties of Al-base alloys so that progress can be made toward extending their present applications in the aircraft industry. Al-Zn-Mg is precipitation hardened to gain its high strength; however, during aging the formation of heterogeneous precipitates on the grain boundaries creates a precipitate-free zone in the adjacent region. Since high angle grain boundaries are not easily characterized, it is difficult to establish a relationship between the precipitate and the boundary structure. Therefore, this study involves precipitation on low angle grain boundaries where the boundary and the precipitate can be fully analyzed.

Aside from the familiar story of Vorticists and Imagists before the war, no detailed analysis of manifestos in Britain (or Ireland) exists. It is true that, by 1914, there had been such an upsurge in manifesto writing that a review of BLAST in The Times (1 July 1914) began: ‘The art of the present day seems to be exhausting its energies in “manifestoes.”’ But after the brief fire ignited by the arrival of Italian Futurism died out, Britain again became a manifesto-free zone. Or did it? While a mania for the militant genre did not take hold in Britain and Ireland the same way it did in France, Italy, Germany, or Russia, the manifesto did enjoy a small but dedicated following that included Whistler, Wilde, and Yeats; Patrick Geddes and Hugh MacDiarmid; Wyndham Lewis and Ezra Pound; Dora Marsden and Virginia Woolf; and Auden, MacNeice, and Spender. Through these and other figures it is possible to trace the development of a manifesto tradition specific to Britain and Ireland.

UK involvement in the EU Area of Freedom, Security, and Justice (AFSJ) has been patchy. It never joined the Schengen border-free zone, and when in 2014 it exercised a block exit from all AFSJ measures, it selectively rejoined a substantial number. Even if partially outside, the UK has been a leader inside. Advanced intelligence capabilities meant it provided important support to the functioning of agencies such as Europol and UK laws inspired EU laws, for example, on data retention. The need to preserve some pragmatic forms of cooperation between the UK and the EU is obvious and shared by the UK security establishment. There is a partial institutional precedent . When Denmark rejected participation in Europol in a popular referendum, the Danish government obtained a deal from the EU institutions which allows it to remain associated to Europol as a ‘third country’ (and a Member State). The bespoke Brexit reality may prove even more complex.

AbstractChromium is normally added to liquid alloy in the form of different grades of ferrochromium (FeCr) alloys for the requirement of different alloy grades, such as stainless steels, high Cr cast iron, etc.. In this work, inclusions in two commercially produced alloys, i.e., high-carbon ferrochromium (HCFeCr) and low-carbon ferrochromium (LCFeCr) alloys, were investigated. The FeCr alloy/liquid iron interactions at an early stage were investigated by inserting solid alloy piece into contact with the liquid iron for a predetermined time using the liquid-metal-suction method. After quenching these samples, a diffusion zone between the alloys and the liquid Fe was studied based on the microstructural characterizations. It was observed that Cr-O-(Fe) inclusions were formed in the diffusion zone, FeOx inclusions were formed in the bulk Fe, and an “inclusion-free” zone was detected between them. Moreover, it was found that the HCFeCr was slowly dissolved, but LCFeCr alloy was rapidly melted during the experiment. The dissolution and melting behaviors of these two FeCr alloys were compared and the mechanism of the early-stage dissolution process of FeCr alloys in the liquid Fe was proposed.
