Solute trapping in Al-Cu alloys caused by a 29 Tesla super high static magnetic field

摘要

Cu is corrected to be 4.3123?? and 4.2628?? for Al-40?wt.%Cu alloys treated without and with a SHSMF. The spacing of (111) plane in Al is corrected to be 2.3351?? and 2.3258?? for Al-26?wt.%Cu alloys treated without and with a SHSMF. The compression yield strength has been improved by about 42% from 268?MPa to 462?MPa for Al-26?wt.%Cu and 42.5% from 248?MPa to 431?MPa for Al-40?wt.%Cu. The maximum elastic strain increases from about 2% to 4.3% for Al-26?wt.%Cu and from 2% to 4% for Al-40?wt.%Cu. It is expected that SHSMF is beneficial to process materials with high mechanical properties.
