By using the calculated results of EET theory, the local valence electron structure elements of residual chemical bonds of Al-Si and Mg-Al alloy melts, that is, the residual bond structure models, were established. From the viewpoint of effect of pressure on melt structure, the essential reason of deviation phenomenon for maximum solution point and eutectic point in thermodynamics equilibrium phase diagram was analysed. Moreover, under pressure condition, the change of thermodynamics equilibrium phase diagram was macroscopic reflection of microstructure change of alloy melt.

X-ray radiography, X-ray radioscopy and X-ray computed tomography were performed to the C preforms and C/SiC composites made by chemical vapor infiltration method. Elementary research of the simulation of X-ray nondestructive testing of C preforms and C/SiC composites was conducted. The main contents and conclusions are summarized as follows:(1) The equivalent absorption coefficients of graphite and SiC to Al (KAl/sic, KAI/C) were measured. It was found that in 35-45KV, KAl/sic=1.1~1.2 and KAl/c=0.08~0.12. That means X-ray radiography was much less sensitive to fiber defects than to SiC matrix. It was suggested that Al Image Quality Indicator would be used to evaluate the quality of X-ray radiographs of C/SiC.
本文选择X射线照相、X射线实时成像和X射线CT等三种方法对C纤维预制体及C/SiC复合材料进行了检测和研究,并对C/SiC复合材料X射线检测的计算机模拟做了初步的探索,主要研究内容和结果如下:(1)测定了C和SiC的X射线照相等效系数,在35~45KV的条件下,Al对SiC的等效系数K_为1.1~1.2,Al对C的等效系数K_为0.08~0.12,所以X照相射线检测C/SiC对C纤维缺陷不敏感,而对SiC基体缺陷敏感。
