is the spinodal decomposition. The mechanisms of early precipitation of L12 phase and D022 phase in Ni-12.5%Cr-7.5% Al alloy are both the non-classical nucleation and growth. The coarsening process... precipitation process 4 Conclusions 1) Ni-17%Cr-7.5% Al and Ni-12.5%Cr-7.5% Al are aged at 900 K. In the early stage of precipitation, L12 and D022 phases present non-directional and irregular shape......

Isothermal precipitation and growth process of perovskite phase in oxidized titanium bearing slag WANG Ming-yu(王明玉)1, WANG Xue-wen(王学文)1, HE Yue-hui(贺跃辉)2, LOU Tai-ping(娄太平)3, SUI Zhi-tong(隋智通)3... and use the slag lies in separation of perovskite efficiently. The precipitation of perovskite phase in molten slag is a complex dynamics process, and attracts more attention with its gradually important......
simulated. The results show that the early precipitation mechanism of L12 phase is the mixed mechanism of spinodal decomposition and non-classical nucleation growth, whereas the early precipitation mechanism of DO22 phase is spinodal decomposition when the pre-aging temperature is 873 K. The early precipitation mechanism of L12 phase is non-classical nucleation growth, whereas the early precipitation......
for understanding the morphology, is much less mature compared with the thermodynamics and kinetics of precipitation. The morphology of precipitates is developed through the process of nucleation and growth... with the orientation relationship (OR) allowing low energy interface are likely favored. Usually, there exists an elastic strain field around each precipitate in the early stage of precipitation. The strain......
. K-means algorithm is simple and has high efficiency when used for the early identification process of network traffic, while there are also some deficiencies. 2.1 K-means algorithm K-means algorithm...; (3) where VFP and VFN denote the values of false positive and false negative, respectively. In the early recognition process of network traffic, the lower FP and FN are very important......
