Process for preparing aluminum/lithium/scandium rolled sheet products |
摘要 |
Aluminum/lithium alloys displaying excellent weldability while also exhibiting isotropic physical properties is produced by including greater than 0.25 weight percent scandium and processing by a combination of low temperature hot working, recrystallization, optional cold working, and artificial aging. The alloy materials are particularly useful as aircraft and spacecraft components such as fuel tanks.
