and the crystalline states of the as-spun alloys were examined by TEM as shown in Fig.3. It can be seen that the as-spun (10 m/s) Zr0 alloy exhibits a nano-crystalline and microcrystalline structure. The electron... alloys were prepared by ion etching for observing the grain morphology with TEM (JEM-2100F), and for determining crystalline state of the samples with selected area electron diffraction (SAED). 2.3......
