Sports mega-events as part of a nation's soft power strategy: The cases of Germany (2006) and the UK (2012)

The potential positive impact on a nation's image has moved from being a welcome consequence to a significant justification for investing in hosting sports mega-events. Mobilising Joseph Nye's concept of 'soft power' we empirically investigate Germany's strategic use of a sports 'mega' (the 2006 FIFA World Cup) to successfully alter their image among 'foreign publics'. We then analyse the example of the London 2012 Olympic and Paralympic Games for Britain's international prestige. For both cases we draw on and analyse official government documents and newspaper sources written before and after the Games. The findings reveal the stark contrast between Germany's and Britain's sport and 'soft power' strategies: the former undertook a long-term, well-planned and resourced approach to altering its poor international image; the latter appeared far less concerned about capitalising on the Olympics to enhance Britain's (seemingly robust) international image

Design of Wear-Resistant Austenitic Steels for Selective Laser Melting

Type 316L stainless steel feedstock powder was modified by alloying with powders containing carbide/boride-forming elements to create improved wear-resistant austenitic alloys that can be readily processed by Selective Laser Melting. Fe-based alloys with high C, B, V, and Nb contents were thus produced, resulting in a microstructure that consisted of austenitic grains and a significant amount of hard carbides and borides. Heat treatments were performed to modify the carbide distribution and morphology. Optimal hard-phase spheroidization was achieved by annealing the proposed alloys at 1150 °C for 1 hour followed by water quenching. The total increase in hardness of samples containing 20 pct of C/B-rich alloy powder was of 82.7 pct while the wear resistance could be increased by a factor of 6
