Pressure-induced preferential growth of nanocrystals in amorphous Nd(9)Fe(85)B(6)

Abstract:
Control over the growth and crystallographic orientation of nanocrystals in amorphous alloys is of particular importance for the development of advanced nanocrystalline materials. In the present study, Nd(2)Fe(14)B nanocrystals with a strong crystallographic texture along the [410] direction have been produced in Nd-lean amorphous Nd(9)Fe(85)B(6) under a high pressure of 6 GPa at 923 K. This is attributed to the high pressure inducing the preferential growth of Nd(2)Fe(14)B nanocrystals in the alloy. The present study demonstrates the potential application of high-pressure technology in controlling nanocrystalline orientation in amorphous alloys.

To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
