摘要: — The influence of age-hardening on the middle and low crack growth rates a 7075 Al alloy is studied in vacuum. A transition fracture surfaces morphology curves observed with T 651 7351 treatments near-threshold regime. Measurements closure show its dependance roughness explain lack ΔKth load ratio, except for alloy. An equation rate to fourth power ΔKeff good agreement only propagation obtained microstructure an homogeneous deformation mode.
