Hydrogen Storage Characteristics of Mechanically Ball Milled MgH

3 Hydrogen Storage Characteristics of Mechanically (Ball) Milled MgH  

As discussed in Sect. 1.3, the major objective of mechanical (ball) milling is to obtain a substantial nanostructuring of hydrides (nanohydrides), which in effect can 

1 Microstructural Evolution During Milling and Subsequent Cycling of Commercial MgH Powders 

In the context of this book, the name commercial MgH will be used to describe any MgH powder purchased from a supplier of chemicals, the prime examples of 

the breadth of the XRD peaks of p-MgH increases with increasing milling time. As discussed in Sect. 1.4.3, this is related to the formation of crystallites (nanograins) within the powder particles, which may be accompanied by the introduction of lattice strains. Table 2.8 lists nanograin size and lattice strain of P-MgH as a fnnction of milling time estimated from the procedure described in Sect. 1.4.3.
