of Yb addition on the strength and fracture toughness of Al-Zn-Mg-Cu-Zr aluminum alloy was investigated by measuring tensile properties and fracture toughness. The surface morphology was observed.... Tensile properties and fracture toughness were measured by a CSS-44100 testing machine. Volume electric conductivity was tested by a SX1931 digital micrometer (four-probe method). The samples......
. The fracture of the inclusion particles is induced when the accumulation of cyclic loading reaches the ultimate tensile strength[12]. In Figs.3(c) and (d), thousands of inclusion particles are located near...
