Coupling effect of multiple precipitates on the ductile fracture of aged Al–Mg–Si alloys
The coupling effect of multiple precipitates on the mechanical properties of an Al–Mg–Si alloy was investigated by experiment and modeling. A density-dependent superposition effect of multiple precipitates on yield strength was observed, differing from simple addition. Using a multiscale fracture mo...

| description | The coupling effect of multiple precipitates on the mechanical properties of an Al–Mg–Si alloy was investigated by experiment and modeling. A density-dependent superposition effect of multiple precipitates on yield strength was observed, differing from simple addition. Using a multiscale fracture model, the coupling effect of multiple precipitates on the strain to fracture was also revealed to be a density-dependent superposition of the individual types of precipitate, essentially similar to that for yield strength. |
