摘要

This study reports experimental results and analysis of the amorphization reaction in an engineering Al alloy (Al 94 wt%) during mechanical milling in a liquid nitrogen environment (cryomilling). We propose that the amorphization reaction occurred as a result of the magnitude of the strain field during cryomilling and the presence of a low temperature (e.g., 88 K). These two factors provided the driving force for the crystalline-to-amorphous transition and helped maintain the amorphous phase below the glass transition temperature.View full textDownload full textKeywordsball-milling, nanostructured materials, amorphous alloys, aluminum alloysRelated 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/10.1080/09500839.2012.658877
