THREE-DIMENSIONAL AND CROSS-SECTIONAL CHARACTERISTICS OF NORMAL GRAIN GROWTH BASED ON COMPUTER SIMULATION
基于计算机模拟的正常晶粒长大的三维特征和二维截面表征

An appropriate Monte Carlo method was developed to simulate the three-dimensional normal grain growth more completely comparative investigation on the three-dimensional characteristics and the cross-sectional expressions of normal grain growth indicated that the time exponent of grain growth determined from cross-section exhibits the same rule of increasing slowly with time and approaching the theoretical value n=0.5 of steady grain growth as the 3-D systemi from change of the number of grains per unit area measured in cross-section with time the state of three-dimensionaInormal grain growth may be predicted; the grain size distribution in cross-section is difFerent from that in three-dimensional system and cannot express the evolution characteristic of the three-dimensionaldistributioni there exists statisticat connection between the topological parameters in cross-section and those in three-dimensions.
