To measure internal strains in an Al MMC, time-of-flight (TOF) ncutron diffraction was used on the ENGIN instrument at ISIS, RAL, in Oxfordshire, and a monochromated X-ray beam was employed on the BM16 beamline at the ESRF in Grenoble. The development of intergranular stresses between groups of grains possessing certain crystallographic orientations was studied using diffraction of penetrating radiation. Due to aluminum's highly isotropic elastic modulus, the variation of measured strains in ...
