✦ Synopsis

In situ neutron-diffraction technique has been employed to study the uniaxial tensile deformation of a bulk nanocrystalline Ni-Fe alloy. In contrast to an increase in the full-width half-maximum (FWHM) of the neutron-diffraction patterns for the coarse-grained Ni, the FWHM for the nanocrystalline Ni-Fe alloy decreases with increasing the plastic strain, Ξ΅ P . The deformation with Ξ΅ P < 1.5% did not introduce a residual lattice strain and a texture in the nanocrystalline Ni-Fe alloy, which were otherwise developed in the coarse-grained Ni.

The tensile behavior of a Ti-11%Zr-14%Nb-10%Sn alloy with pure orthorhombic Λ› phase was studied by in situ X-ray diffraction using synchrotron radiation. It is found that no phase transformation happens during the whole tensile process. The "double-yielding" platforms of this alloy are indeed due to

A stress rig is constructed to make in situ neutron diffraction possible on tensile test specimens. The lattice spacing of the (1 10) reflection of a ferritic steel having nonuniform cross-section is measured both parallel and perpendicular to the applied stress. The apparent stresses are calculated

The internal stress developments of B2 compounds NiAl, CuZn, and CeAg are examined using in situ neutron diffraction. CeAg is a representative of a newly discovered class of fully ordered and ductile B2 compounds. Using polycrystal plasticity modeling to interpret the results, it is revealed that th
