Abstract
The present disclosure relates to methods for producing new 6xxx aluminum alloy sheet products having tailored precipitate phase particle size distributions. The tailored precipitate phase particle size distributions may be produced by preparing a 6xxx aluminum alloy sheet for precipitate phase modification, and then modifying an initial precipitate phase particle size distribution of the material. The modifying may include heating the intermediate gauge strip to a temperature of from 440° C. (825° F.) to 500° C. (932° F.) and for a time sufficient to create a modified strip product having a modified (tailored) precipitate phase particle size distribution. The modified strip product may realize improved properties.
