analysis. The introduction of hydrogen into brass lattice results in expanding of its lattice causing change in the
interplanar spacing. The higher charging current density and longer charging time applied to this material, the greater the
lattice distortion producing higher residual stresses. Increasing the current density or charging time in the material caused
the brass lattice to continue to expand as indicated by measuring the relative volume change. It was found that the
interplanar spacing and line breadth of brass peaks increased with either current density or charging time.]]>Hagi, H.,199639248248Troiano, A.R.,1960525480Van Leeuwen, H.P.,19746141161Ulmer, D.G. and C.J.
