摘要

Experimental measurements of stress drops and band strains in type-B Portevin-Le Chatelier (PLC) bands were carried out for 5xxx series Al-Mg sheets with Mg content between 1.8 and 4.5 wt%. While the stress drops increase with global strain, the band strain values in all the samples follow a common linear relationship with global strain. The results indicate that the type-B PLC band strain is independent of solute content at given strain rate.View full textDownload full textKeywordsPortevin-Le Chatelier effect, Portevin-Le Chatelier band strain, dynamic strain aging, serrated flow, digital image correlationRelated 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/10.1080/09500839.2012.714082
