Stabilizing γ‐MgH 2 at Nanotwins in Mechanically Constrained Nanoparticles

Super-strengthening and stabilizing with carbon nanotube harnessed high density nanotwins in metals by shock loading

CNTs reinforced metal composites has great potential due to their superior properties, such as light weight, high strength, low thermal expansion and high thermal conductivity. The current strengthening mechanisms of CNT/metal composite mainly rely on CNTs' interaction with dislocations and CNT's intrinsic high strength. Here we demonstrated that laser shock loading the CNT/metal composite resu...

Nucleation of amorphous shear bands at nanotwins in boron suboxide

The roles of grain boundaries and twin boundaries in mechanical properties are well understood for metals and alloys. However, for covalent solids, their roles in deformation response to applied stress are not established. Here we characterize the nanotwins in boron suboxide (B6O) with twin boundaries along the {0111} planes using both scanning transmission electron microscopy and quantum mecha...

Stabilizing nanostructured materials by coherent nanotwins and their grain boundary triple junction drag

Mechanically Sintered Gallium#x02013;Indium Nanoparticles

DOI: 10.1002/adma.201404790 plowed pile of chips formed from a dried fi lm of EGaInNPs (see Experimental Section). Note the occurrence of microcracks in the deposits in Figure 1 , which is common in dried colloidal deposits. [ 21,22 ] Furthermore, the stability of the chips indicates “solid-like” behavior of the deposit and high interparticle adhesion, both characteristic of the oxide coating e...

Patterning of martensitic nanotwins

We perform the atomistic Monte Carlo simulations of formation of nanostructured martensites in nickel–titanium thin films. The results reveal the atomistically resolved patterning of martensitic nanotwins, including coarsening, branching and twinning within twins, as mediated by temperature and substrate constraints. A scaling law is derived to elucidate the physical effects governing the chara...
