The neutron diffraction has recently been used for studies on strength of materials as well as material design and processing. The principles of such studies are almost identical with those for X-ray diffraction; diffraction profile analyses provide elastic lattice strain, domain size, and micro strain associated with lattice defects. Because the penetrating ability of neutron is much higher than that of X-ray, we can obtain three-dimensional information on bulk samples by neutron scattering. Our recent works using neutron Angle Dispersion (AD) and Time of Flight (TOF) methods are briefly reviewed. The topics include residual phase stresses caused by thermal history and/or inhomogeous plastic deformation for SiCw/A2014 MMCs and α-γ Fe-Cr-Ni alloys, in situ diffraction during tension-compression deformation in the Fe-Cr-Ni alloys or during shape memory behavior in an Fe-Mn-Si-Cr alloy.
