Methods and systems to predict fatigue life in aluminum castings

InactiveUS20090276166A1Accurately fatigue propertyAccurate of fatigue propertyPlug gaugesDigital computer detailsCrazingCasting defect
Methods and systems of predicting fatigue life in aluminum castings that combines extreme values of both casting flaws and microstructures with multiscale life models. The multiscale life models account for differing fatigue crack initiation based on the size scale of the defect and microstructure features, including provisions for generally millimeter scale casting flaws, generally micrometer scale second phase particles by cracking or debonding, or submicrometer scale dislocation interactions with precipitates which form persistent slip bands. In the presence of casting flaws, the fatigue initiation life is negligible and the total fatigue life is spent in propagation of a fatigue crack from such flaws. In the absence of casting flaws, however, the total fatigue life is spent in both crack initiation and propagation, except for the case where fatigue cracks initiate from large second phase particles in a coarse microstructure. The extreme values of casting flaws, second phase particles, mean free path through an aluminum matrix or grain sizes are obtained from extreme value statistics when two or three dimensional sizes of casting flaws and microstructure features are provided by either direct measurement or analytical prediction. The upper bound flaw or microstructure feature size is calculated by extreme value statistics.

Heat treatment method for improving fatigue resistance of Al-Cu-Mg alloy

A heat treatment method for improving fatigue resistance of Al-Cu-Mg alloy comprises: performing high-temperature short-time (505-535 DEG C / 1-25 min) solution hardening treatment on cold-rolled sheets, then performing natural aging at room temperature for 96 h or more. The aluminium alloy capable of being treated by the heat treatment method comprise the components: Cu, Mg, Ti and Al. The technology is simple and reasonable; and through high-temperature short-time solution hardening treatment, the alloy obtains relatively high goss texture components. Because most of crystal faces {111} of crystal grains in the alloy with high goss texture is positioned or close to the direction of the maximum external shearing stress, the reciprocating sliding of dislocation is promoted and a persistent slip band is easy to generate in the alloy, and thus the plasticity induction closure effect of fatigue crack is enhanced and the damage accumulation is reduced, also the crack deflection is promoted, and thus the fatigue crack spreading rate of the alloy is reduced and the fatigue resistance of the alloy is improved.
