摘要：

Internal strains within a polycrystalline magnesium alloy plate have been measured during tensile and compression testing in situ by neutron diffraction. Using an elasto-plastic self-consistent simulation code, information about the operation of slip and mechanical twinning modes as a function of strain has been obtained.
