The temperature dependence of the elastic moduli was estimated from ultrasound time of flight measurements performed on bulk metallic glasses of composition Zr63âx Cu24Al x Ni10Co3. Using the corresponding values at the glass transition temperature, the local atomic strain was determined. The obtained values for the critical atomic strain calculated for 8 at%ââxââ15 at% are close to the predicted universal criterion derived from a topological model, but may also reflect the difference in the chemical interaction that are not accounted by a topological approach.View full textDownload full textKeywordsbulk metallic glasses, elasticity, local atomic strain, glass transitionRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/09500839.2011.616181

机译：弹性模量与温度的关系是通过对Zr 63∠x Cu 24 Al x Ni 10 Co 3 。使用玻璃化转变温度下的相应值，确定了局部原子应变。为8 at％x×15 at％计算的临界原子应变的获得的值接近于从拓扑模型得出的预测通用准则，但也可能反映出拓扑方法无法解释的化学相互作用。查看全文下载全文关键字金属玻璃，弹性，局部原子应变，玻璃化转变相关的var addthis_config = {ui_cobrand：“泰勒和弗朗西斯在线”，service_compact：“类同义词，网络振动，推特， technorati，delicious，linkedin，facebook，stumbleupon，digg，google，more“，发布：” ra-4dff56cd6bb1830b“};添加到候选列表链接永久链接http://dx.doi.org/10.1080/09500839.2011.616181
