Phase diagram of binary system C12Zn-C18ZnKezhong Wu, Xindong Wang, and Xiaodi LiuMetallurgy School, University of Science and Technology Beijing, Beijing 100083, ChinaDepartment of Chemistry, Hebei.... The experimental binary phase diagram of C12Zn/C18Zn was established by means of differential scanning calorimetry (DSC) and X-ray diffraction. In the phase diagram a stable solid compound (n-C12H25NH3......

Ag-Pb-Sn三维相图的绘制方法白平平,刘大春,孔令鑫,马明煜,胡亮,杨斌昆明理工大学真空冶金国家工程实验室,云南省有色金属真空冶金重点实验室摘 要:借助MATLAB软件,分别调用插值函数(griddata)编写程序绘制Ag-Pb-Sn三维相图-插值法和回归函数(regress)编写程序绘制三维相图-拟合曲面方程法.结果表明:插值法得到的三维相图液相面很不光滑,局部波动很大,不能显示出相邻相区的析晶线和共晶点;拟合曲面方程法得到的液相面相对光滑,并能清晰的显示出相邻相区的析晶线和共晶点,拟合出的(Ag),Ag5Sn,Ag3Sn,(Pb),(Sn)等相区曲面方程的可决系数r2分别为1.0000,0.9819,0.9855,0.9872,0.9713,说明拟合出的曲面方程是可信的.为了进一步验证拟合出液......
Room Temperature Section of Al-In-Sn Ternary Phase Diagram区向丽,庄应烘摘 要:<正> The X-ray powder diffraction method was used to determine the room temperature section of Al-In-Snternary phase diagram.The section consists of 5 single-phase regions,7 two-phase regions and 3 three-phaseregions.The structure of In3Sn phase is known to be tetragonal......
