Abstract: A ternary function to describe the grain orientation distribution was proposed for the first time. Meanwhile, a systematic and novel method was further established with a special cycle adjustment algorithm to construct real digital microstructures of nanocrystalline materials considering the coupled grain size and grain orientation distributions. This method is very convenient to be used for the application of finite element methods and molecular simulations. [ABSTRACT FROM AUTHOR]
