School of Science, Beijing University...: The structural defects of L10 FePt are investigated by the molecular dynamics (MD) with a modified analytic embedded-atom method (MAEAM). The L10 ordered structure of FePt is relaxed from a trial fcc structure......
3D anisotropy simulation of dendrites growth with phase field method HOU Hua(侯 华)1, ZHAO Yu-hui(赵宇辉)2, NIU Xiao-feng(牛晓峰)1 1. College of Materials Science and Engineering, North University...: The anisotropy problem of 3D phase-field model was studied, and various degrees of anisotropy were simulated by numerical calculation method. The results show that with the change of interface......
for validation purpose, which indicates that the method is reliable for prediction of VLE of Sn-based alloy systems. The experimental conditions for separating Sn-based alloys by vacuum distillation...; (20) 式中:n为实验数据个数;ai,exp和ai,cal分别为活度的实验值和计算值. 表7 无限稀活度因子法计算获得的B参数[18] Table 7 Parameters of B obtained by infinite dilute activity coefficient method[18......
exponents (largest LEs) method was introduced into PGS. By experimental tests conducted using the same dataset, its prediction performance was compared with traditional wavelet neural network (WNN) method in both one-step and multi-step processes. Based on the results, a new multi-step forecasting model called WNN-LE method was proposed, where WNN, which enjoys a more accurate performance along......
