It is shown that the compressive plasticity of a metallic glass, namely Zr52.5Ni14.6Al10Cu17.9Ti5, can be improved by the introduction of two symmetrical notches. The enhanced plasticity may be ascribed to a blocking effect of the propagation of shear bands caused by large stress gradients around the notches. In contrast to ceramic specimens with similar notches, the plasticity enhancement of metallic glass induced by notches can provide a new approach to understanding its unique mechanism of deformation.View full textDownload full textKeywordsmetallic glass, shear bands, notches, plasticity, deformationRelated 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/10.1080/09500839.2010.512573

机译：结果表明，金属玻璃的压缩塑性，即Zr 52.5 Ni 14.6 Al 10 Cu 17.9 Ti 5 ，可以通过引入两个对称槽口来改进。增强的可塑性可归因于由切口周围的大应力梯度引起的剪切带传播的阻挡作用。与具有类似缺口的陶瓷试样相比，缺口引起的金属玻璃的塑性增强可以提供一种新的方法来了解其独特的变形机理。查看全文下载全文关键词金属玻璃，剪切带，缺口，塑性，变形相关var addthis_config = { ui_cobrand：“ Taylor＆Francis Online”，service_compact：“ citeulike，netvibes，twitter，technorati，delicious，linkedin，facebook，stumbleupon，digg，google，更多”，发布：“ ra-4dff56cd6bb1830b”};添加到候选列表链接永久链接http://dx.doi.org/10.1080/09500839.2010.512573
