Manufacturability Improvement of Fiber Aluminum Laminate by Forming the Effective Crystallographic Texture in V95 Alloy Sheets

Abstract

Theoretical notions and formation modes of the crystallographic texture of the sheets made of the V95pch aluminum alloy, which provides the intensification of formation of detail made of fiber aluminum laminates by stretch-forming. The deformation texture (orientations S and Bs) is formed during hot rolling; it enhances during further cold rolling. The recrystallization texture is formed during annealing (orientations {011}〈100〉 and {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.
