Ultrastrong Mg Alloy via Nano-spaced Stacking Faults

Stacking Faults in Co-Alloy Longitudinal Media

Stacking faults in CoCrTa/Cr, CoCrPt/NiAl, and CoCrPt/Cr/NiAl films have been studied by electron diffraction. Interfacial lattice match and epitaxial growth play important roles in reducing the stacking fault density. It is found that the bicrystal media has large stacking fault densities. In the unicrystal media case, when good epitaxy between magnetic layer and underlayer cannot be achieved,...

New horizon for high performance Mg-based biomaterial with uniform degradation behavior: Formation of stacking faults

Designing the new microstructure is an effective way to accelerate the biomedical application of magnesium (Mg) alloys. In this study, a novel Mg-8Er-1Zn alloy with profuse nano-spaced basal plane stacking faults (SFs) was prepared by combined processes of direct-chill semi-continuous casting, heat-treatment and hot-extrusion. The formation of SFs made the alloy possess outstanding comprehensiv...

Luminescence related to high density of Mg-induced stacking faults in homoepitaxially grown GaN

Stacking Faults and Their Effect on Magnetocrystalline Anisotropy in Co and Co-Alloy Thin Films

Stacking faults in (1010) unicrystal Co and Co-alloy thin films have been analyzed by the electron diffraction technique. As predicted no diffraction contrast of stacking faults could be observed when the beam is parallel to the [1010] direction. However, both by plan-view TEM observation and electron diffraction along the [1120] direction reveal that the stacking fault density in biased pure C...

On the energy of terminated stacking faults

The equilibrium of dissociated dislocations is discussed in terms of intrinsic material properties such as the ideal stacking fault energy (ideal SFE) and the stacking fault (SF) strain. The ideal SFE is de® ned as the energy per unit area of an in® nitely extendedSF in an ideal in® nite crystal. The e€ ective SFE is de® ned as the energy per unit area of a terminated SF. The terminated SF is a...
