Study on strength and fracture toughness of Al-Zn-Mg-Cu-Ti(-Sn) alloys
The strength and fracture toughness of Al-Zn-Mg-Cu-Ti(-Sn) alloys were investigated by performing tensile and plane strain fracture toughness (KIC) tests. Detailed observations with optical, scanning electron and transmission electron microscopy were conducted to analyze microstructure and...

| description | The strength and fracture toughness of Al-Zn-Mg-Cu-Ti(-Sn) alloys were
investigated by performing tensile and plane strain fracture toughness (KIC)
tests. Detailed observations with optical, scanning electron and transmission
electron microscopy were conducted to analyze microstructure and fracture
surfaces of the alloys. The results revealed that addition of Sn refined the
solution-aging grain size of matrix and reduced coarsening rate of
precipitate during aging. Narrower precipitation free zones and more
discontinuous distribution of grain boundary precipitates were observed to be
displayed in the Sn-containing alloy. Small size second phase particles Mg2Sn
were observed to form in the Sn-containing alloy and distribute in the fine
dimples of fracture surface. These features of microstructure were believed
to impart higher strength and fracture toughness of the Sn-containing alloy
on overaging. |
