High Plasticity and Substantial Deformation in Nanocrystalline NiFe Alloys Under Dynamic Loading.
A nanocrystalline (NC) NiFe alloy is presented, in which both highly improved plasticity and strength are achieved by the dynamic-loading-induced deformation mechanisms of de-twinning (that is, reduction of twin density) and significant grain coarsening. This work highlights potential ingenious avenues to exploit the superior behavior of NC materials under extreme conditions.
