| Abstract: | The feature of fracture morphology and microdefect has b.een evaluated and characterized for the rare earth-zirconium alloy. The results show that the crack and the hole are the primary microdefect of fracture. And the intergranular morphology, the polygonal morphology and the fan-shaped cleavage morphology are the main fracture morphologies. |
