A manufacturability improvement of glass-fiber reinforced aluminum laminate by forming an effective crystallographic texture in V95 alloy sheets

Abstract

Theoretical notions and formation modes of the crystallographic texture of sheets made of the V95pch aluminum alloy, which intensifies the formation of parts made of glass-fiber reinforced aluminum laminates by stretch forming, are presented. The deformation texture (orientations S and Bs) is formed during hot rolling; it becomes stronger during further cold rolling. The recrystallization texture is formed during annealing (orientations [011]〈100〉, [023]〈100〉). An increase in the limiting stretch-forming coefficient after cold rolling is provided by two-stage annealing, which includes rapid heating at the continuous heat treatment line and subsequent complete annealing in an in-and-out furnace with slow cooling.
