采用ＴＥＭ研究了离心铸造和挤压铸造的ＳＩＣP／ＺＬ１０９复合材料中ＳＩＣ／ＡＩ的晶体学位向关系对１２个ＳｉＣ／ＡＩ位向关系的测量结果表明，虽然ＳｉＣ与ＡＩ之间无固定的晶体学位向关系，但出现了如下优先位向关系：（１１０３）ｓｉｃ／／（１１１）ＡＩ，［１１２０］ｓｉｃ／／［１１０］ＡＩ．（０００１）ｓｉｃ／／｛１１１｝Ａｌ不是优先出现的位向关系讨论了生成（或生不成）有关位向关系的原因
The crystal orientation relationship of SIC / AI in SICP / ZL109 composites by centrifugal casting and squeeze casting was studied by TEM. The results of the measurement of the orientation relationship of 12 SiC / AI indicate that although there is no fixed crystallographic position between SiC and AI To the relationship, however, the following priority relationships have emerged: (1103) sic // (111) AI, [1120] sic // [110] AI. (0001) sic // {111} Al is not a preemptive bit-wise relationship The reason for generating (or not) a bit-oriented relationship is discussed
