•    Description:  The 14th article in a series focused on extrusion defects addresses the influence ofmetallurgical changes during extrusion of 6xxx series alloys. The article references ingot metallurgical effects on extrusion parameters and the influence such effects can have on extrusion throughput (extrudability) and potential defects. The two aspects to consider are ingot product quality as assessed by producer (on-line inspection, release tests, results of extrusion trials) and customer’s assessment (response to treatments and processes carried out by the extruder, performance in service). Descriptions of the quality of the extruded product and billet quality aspects (casting, homogenization, preheating, extrusion, cooling, and aging) are included.
