Title:
ALUMINUM MICROSTRUCTURE FOR HIGHLY SHAPED PRODUCTS AND ASSOCIATED METHODS
Document Type and Number:
WIPO Patent Application WO/2017/105916
Kind Code:
A9
Abstract:
Aluminum and aluminum alloy microstructures that are adapted for improved performance during shaping and forming production processes. Lower relative ratios of alpha fibers, particularly low-end alpha fibers, to beta fibers promotes improved formability of aluminum sheet or blanks without negatively impacting material strength. Beta fibers with higher relative ratios of S and Copper texture components improve formability and produce fewer and more uniform distortions during production. The resulting improvements in quality allow for cupping, drawing, wall ironing, shaping, and necking processes to be carried out faster and with reduced rates of spoilage.
