ScholarBank@NUS Repository. https://doi.org/10.1016/j.actamat.2010.02.033 | Abstract: | Systematic deflection measurements with micro-cantilevers and a combinatorial-deposition method have been used to investigate the density change upon crystallization of amorphous Zr-Cu-Al thin films. It is found that, in general, the density change decreases from Cu-/Al-rich compositions to Zr-rich compositions, and the previously reported good glass-forming compositions are found to correspond to global minima of the density change inside respective local eutectic systems. Furthermore, we propose that the general trend of density change as a function of alloy compositions discovered in this work may have implications for the macroscopic plasticity of metallic glasses. © 2010. | Source Title: | Acta Materialia | URI: | http://scholarbank.nus.edu.sg/handle/10635/64843 | ISSN: | 13596454 | DOI: | 10.1016/j.actamat.2010.02.033 |
