摘要：
The mechanical properties and the strain-aging response of two rapidly solidified commercial aluminum alloys, Al-Cr-Zr and Al-Fe-V-Si (FVS0812), have been investigated in tension between 300 and 700 K. A ductility trough is observed between 350 and 550 K. It is associated with a dip in the strain-rate sensitivity (SRS). These results are interpreted in terms of dynamic strain aging (DSA), and through a semiquantitative analysis, the migrating species are tentatively identified as being chromium in the Al-Cr-Zr alloy and iron in the Al-Fe-V-Si alloy.
