Metallurgical features affecting the extrusion of aluminium alloys,cture because of these alloy differences. Typical microstructural features are described in this chapter for each class and show how microstructure progressively develops from the as-cast ingot to the final wrought form (although this is treated in more detail in Chapter 4). Furthermore, alloy class

Extrusion processing,he process variables which may be controlled are the extrusion ratio ., the ram speed .., and the extrusion temperature .. However, the extrusion ratio is generally fixed by customer specification so that the temperature and the speed become the only controllable factors.

Overview of TCLs in Smart Grids,ilable following the invention in 1886, concurrently by Hall and Heroult, of the electrolytic process to extract the metal from bauxite. Among the industrial methods by which aluminium billets can be transformed to exceedingly complex shapes, extrusion has no rival and has firmly established itself
