Residual stress measurements using neutron and X-ray diffractions are applicable to crystalline materials whereas the strain measurement in amorphous materials had been difficult. Recently, Q-space method, which can evaluate the strain from peak shift of 1st halo peak measured by synchrotron X-ray, and Direct space method, which can evaluate the strain from changes in local structures obtained by the radial distribution function, have been reported by Poulsed et al. In this study, the evaluation of tensile deformation in ZrAlNiCu metallic glass using Q-space method was discussed by using neutron diffraction.
