Effects of strain, strain rate and temperature on deformation twinning in a Cu–Zn alloy

Plastic Deformation and Damage Behaviors of Fe-18Cr-18Mn-0.63N High-Nitrogen Austenitic Stainless Steel under Uniaxial Tension and Compression

“…9(c), from which one can see that some large twin-like bands (marked by arrows) tend to be separated into small ones. In fact, Xiao et al 38) also reported quite similar results that with increasing strain, the average twin layer thickness decreased slightly, while the average twin boundary spacing decreased significantly in a Cu-Zn alloy.…”

Mechanism of lamellae deformation and phase rearrangement in ultrafine β-Ti/FeTi eutectic composites

“…Hence, it has been noticed that < e 2 > 1=2 of the AMI composites increase 2-times upon severe forging. The dislocation density (q d ) has been estimated from < e 2 > 1=2 according to the following equation [45]:…”

Nanoscale deformation twinning at ultrahigh strain rates during kinetic spraying of nickel

“…Nanostructures, i.e., nano-sized grains (NGs) and nanoscale twins (NTs) have recently been topics of great interest from both scientific and technological points of view in the engineering of metals and alloys, as mixtures of NGs and NTs generated in bulk materials under specific deformation conditions have demonstrated novel properties, such as high strength with reasonable ductility and improved tribological properties [11][12][13]. It has been reported that NTs were successfully generated in bulk pure Cu and Cu-Zn alloy samples, both of which are face-centered cubic (FCC) metals with low stacking fault energies (SFEs) ( $ 14-45 mJ m À 2 ), by means of a dynamic plastic deformation (DPD) under a dynamic loading impact at strain rates of $ 10 2 -10 3 s À 1 and liquid nitrogen temperature (LNT) [11,12].…”
