摘要：
The dependence of the fracture toughness K 1C of rolled ageing alloys with structural and crystallographic textures on the loading direction is established. A formula describing the anisotropy of the K 1C and including structural parameters of structurally textured alloys on planes of growth of mode I cracks is derived and validated for aluminum alloys. The influence of crystallographic planes and crack growth direction on K 1C is analyzed for titanium alloy as a rolled material with crystallographic texture. © 2009 Springer Science+Business Media, Inc.
