Title: Polycrystalline deformation in engineering materials: Insights from neutron diffraction during loading

Abstract

In situ measurements using the nondestructive penetration of neutrons are commonplace at neutron sources and permit investigations within environmental chambers at stress, pressure, or temperature. Many of these studies explore the microstructural performance of engineering materials under service conditions. For example, by measuring phase strains during the application of static loads, neutron diffraction provides insight into failure, relaxation, and load transfer mechanisms. The authors discuss examples of in situ deformation measurements including the following: (1) Twinning during tensile deformation of a U-6 Nb alloy and (2) Load partitioning at 20 C and at 300 C in a CuMo composite.
