| Abstract Scope |
Many complex concentrated alloys have interesting mechanical properties that are often attributed to distortions of the underlying lattice. However, there is a dearth of detailed quantitative experimental evidence regarding the nature and extent of these lattice distortions. To address this issue, we have performed diffuse x-ray scattering measurements on bulk single crystals of several alloys of increasing compositional complexity, including Ni, FeNiCo, and FeNiCoCr. We interpret the results in terms of three-dimensional pair distribution functions (3D- ΔPDFs) and the corresponding lattice distortions. Finally, we discuss the implications of these measurements for understanding the effect of lattice distortions on mechanical behavior of complex concentrated alloys. |
