Unformatted text preview: hery arrows, and it remains to be established how widespread the use of these alloys will become. As the construction techniques of the advanced trains become more akin to aerospace technology, it could well be that the scandium modified 7xxx alloy could provide some significant system advantage. For example, a higher strength extrusion (due to the addition of a scandium-containing alloy) when used to build a total assembly might enable certain design improvements such as the need for less material resulting in a lighter, more fuel efficient system. Friction Stir Welding: As pointed out in the “Aluminum Industry Technology Roadmap,”17 the technology of aluminum joining has advanced rapidly in recent years. Developments in FSW especially have been most significant and have provided aluminum with a significant competitive advantage in some markets (Figure 7). Since its inception in the early 1990s, FSW has advanced most rapidly with aluminum due to its combination of low melting point, high thermal con...
