The effect of adding Gd to Zr-base bulk amorphous alloy on glass formation ability （GFA）

Structure transformation and thermal characterisation

has been studied by X-ray diffraction （XRD） and Differential scanning calorimetry （DSC）.The result show that the additiong of Gd increased average distance of atom

changed short-range order area

the reduced glass transition temperature Trg （Trg=Tg/Tm）get the bigest value 0.7016 in content of 5% but the supercooled liquid region △Tx decrease from 50.1 to 33.9 when the content of Gd from 1% to 10%.
