understanding of the evolution behavior of equiaxed α phase in Ti-8Al-1Mo-1V alloy during annealing, its static coarsening mechanism was studied based on the calculations of coarsening exponent n and the activation energy for α boundary migration. The result of n=6 indicates a special coarsening mechanism of equiaxed α phase. The activation energy for α boundary migration is calculated to be 138 kJ/mol......

of bimodal microstructure at 1140°C is explored. The data shows formation of a duplex size precipitate microstructure after 5 min of the aging. Formation mechanism of the duplex structure is discussed. Coarsening and dissolution mechanisms at 1120°C are discussed. Precipitates are found to grow up to a critical size in coherent and cubical morphology, beyond which dissolution sets in. 关键词:precipitation......

Cellular automata modelling of grain coarsening during reheating--Ⅱ. Abnormal grain growthE.J.Palmiere,S.P.Banks摘 要:<正>The 2-dimensional cellular automata (CA) simulation technique has been utilized to investigate the abnormal grain coarsening. The growth of abnormal grains is modelled under this assumption that different grains have different......
