热稳定性和 Zr35x Ti30Cu7.5Be27.5Ag x 的玻璃形成能力(GFA )(x = 010 ) 合金被 X 光检查衍射(XRD ) 学习,微分扫描热量测定(DSC ) 和超声的技术。我们发现 1 个 at.% Ag 罐头的增加更加提高在 Zr34Ti30Cu7.5Be27.5Ag1 合金在 Zr35Ti30Cu7.5Be27.5 合金从 15 公里由批评玻璃尺寸的增加显示了到 20 公里的 GFA。然而,与更多的 Ag 的增加 supercooled 液体区域(T x ) 和参数(定义为 T x/T g+T l )) 急速地从 155 K 和 0.436 ~ 76 K 减少了并且 0.363 分别地,在 GFA 导致减少。另外,有弹性的常数(比率砍模量到体积模量或泊松比率) 也被用作一个计量器在 Zr35x Ti30Cu7.5Be27.5Ag x 合金评估 GFA。
The thermal stability and glass forming ability (GFA) of Zr35-xTi3oCu7.sBe27.sAgx (x = 0-10) alloys were studied by X-ray diffrac- tion (XRD), differential scanning calorimetry (DSC) and ultrasonic techniques. We found that the addition of 1 at.% Ag can con- siderably enhance the GFA as indicated by an increase in the critical glass dimension from 15 rnm in the Zr35Ti30CuT.sBe27.5 alloy to 20 mm in the Zr34Ti30Cu7.sBe27.sAgl alloy. However, with the addition of more Ag the supercooled liquid region (ATx) and y parameter (defined as Tx/(Tg+TO) drastically decreased from 155 K and 0.436 to 76 K and 0.363, respectively, resulting in a de- crease in the GFA. Additionally, the elastic constant (the ratio of shear modulus to bulk modulus or Poisson' s ratio) was also used as a gauge to evaluate the GFA in Zr35-xTi30Cu7.sBe27.sAgx alloys.
