| Abstract: | Thefracture processof an ascast ZA27 alloy under thetensiletest atthe room temperature wasstudied. Theresultsshow thatthecracksof ZA27 alloy form at(α+ η)eutectic phaseand develop bypropagatingalongthe(α+ η) phaseandcuttingthroughthe dendriteαphaseand εphase. Theinfluenceof every phasein ZA27 on thestrength and ductility was ana lyzed. |
