Billet Process and Equipment 125 BP New Alloys – Challenges in Casting and Extrusion Processes J.D. Schloz -- Wagstaff, Inc., USA Demand for better product characteristics forces aluminum product managers to adjust alloy chemistries, or change to different alloys. Improved alloy chemistries challenge extruders and casters with increased scrap rates, and require tighter controls over alloy chemistries and industrial practices. Combined metallurgical analysis techniques, including optical microscopy, scanning electron microscopy, and transmission electron microscopy help explain these challenges from a fundamental, metallurgical basis. |
