Abstract
Stacking faults (SFs) are mostly related to the glide of partial dislocations. Cross stacking faults (CSFs) in Zr(Fe,Cr)2 face-centered cubic (FCC) Laves phase nanoparticle (NP) were investigated by transmission electron microscopy (TEM). Our results reveal that CSFs originate from the phase boundary by ⅙ <112> Shockley partial dislocations on crossed close-packed planes simultaneously. More importantly, the driving force of CSFs was further discussed. That is, when the loading direction is parallel or close to <001> directions, the CSFs will be induced in FCC crystals. Knowledge about our investigations will provide a fundamental understanding of the CSFs in FCC crystals.
