J. Cent. South Univ. (2016) 23: 189-200 DOI: 10.1007/s11771-016-3062-8 Theoretical generalization of Markov chain random field from potential function perspective HUANG Xiang(黄翔)1, WANG Zhi-zhong(王志.... MCRF is a special MRF for dealing with high-order interactions of sparse data. It consists of a single spatial Markov chain (SMC) that can move in the whole space. Generally, the theoretical backbone......
of microelements on the microstructural evolution of Al-Ag alloys during initial aging stage. The simulation results suggest that the microelements In, Sn and Be have a dramatic depression effect on the Ag.... In this model, "vacancy-locking" and "vacancy clusters" are two important mechanisms in the aging process. Key words: Al-Ag alloy; kinetic Monte Carlo method; microalloying elements; aging stage  ......
