摘要: Abstract After a description of the evolution Al-Li alloys, this paper first reviews subject anisotropy in mechanical properties wrought products. In plane, through thickness and axisymmetric flow anisotropies present products are defined. The root causes for these discussed. Pros cons arising from anisotropic then discussed context designing manufacturing space aerospace structures. Numerous attempts aimed to reduce rolled extruded summarized. It is concluded that ‘isotropic’ can be manufactured via selection appropriate process, composition processing parameters.
