【 摘 要 】

The residual stress and deformation behavior of a Zr55Al10Ni5Cu30 bulk metallic glass containing 10 vol.% ZrC particles were measured using neutron diffraction. Elastic deformation behavior under uniaxial tensile loading can be predicted by the self-consistent model. The higher strength in compressive deformation in this sample originates from the thermal tensile residual stresses, and from the phase stresses transferred to the metallic glass matrix, which are 5% less than the applied stresses under uniaxial loading.
