Abstract

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.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® 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.
