Elimination of aluminum-lithium sheet anisotropy with SPF forming |
摘要 |
A novel method is disclosed for removing or eliminating anisotropic material properties typically found in conventionally rolled or otherwise processed aluminum-lithium alloy products obtained from conventional aluminum fabrication mills. The method comprises imparting a predetermined amount of strain to the conventionally rolled alloy sheet whereby the alloy experiences dynamic recrystallization. Through this process, the mill-imposed crystallographic texturing, which initially sets up the undesired anisotropic characteristics, is eliminated. A preferred technique for imparting strain to the sheet stock is superplastic forming.
