Investigation on deformation and wear of Zr-based amorphous alloys
Yan, C., Yu, H., Swain, M., Shum, P.W., & Shen, Y.G. (2007) Investigation on deformation and wear of Zr-based amorphous alloys. Materials Forum, 31, pp. 136-138.
Nanoindentation with spherical and Berkovich indenters, reciprocating wear and dynamic impact tests were conducted to investigate the deformation and wear behavior of two Zr-based metallic glasses. The results indicated that the indenter shape may have an effect on the displacement bursts in the load-penetration curves as no apparent bursts could be observed when a Berkovich indenter was used. This possible reason was postulated as the higher stress developed under a Berovich indenter prompting a large number of small shear bands, confirmed by the steps observed around the indents. Compared to Zr55Al10Ni5Cu3 alloy, Zr41.25Ti13.75Ni10Cu12.5Be22.5 has higher resistance to both wear and dynamic impact.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
