【摘要】 利用ＸＲＤ和ＴＥＭ分析研究了(Ａｌ_１８Ｂ_４Ｏ_３３)_ｗ／ＺＬ２０２复合材料中Ａｌ_１８Ｂ_４Ｏ_３３晶须同基体合金ＺＬ２０２之间的界面反应。结果表明，在Ａｌ_１８Ｂ_４Ｏ_３３晶须和ＺＬ２０２之间存在界面反应，界面反应物为具有尖晶石结构的ＣｕＡｌ_２Ｏ_４，并发现反应物同晶须之间存在如下的位向关系：｛１１１｝_{Ａｌ１８Ｂ４Ｏ３３}‖｛１１１｝_{ＣｕＡｌ２Ｏ４}，＜２１１＞_{Ａｌ１８Ｂ４Ｏ３３}‖＜１１２＞_{ＣｕＡｌ２Ｏ４}。文中还对界面反应机制进行了分析。更多还原

【Abstract】 Using XRD and TEM analysis,the interfacial reaction in Al₁₈B₄O₃₃w/ZL202 composite was studied, the results indicate that there exists interfacial reaction in the composite,the product of the interfacial reaction is CuAl₂O₄ with spinal structure.The orientation relationship between the whisker and CuAl₂O₄ was determined as{111}_Al18B4O33‖{111}_CuAl2O4, <211>_Al18B4O23‖<112>_CuAlO4.The mechnism of the interfacial reaction was also discussed.更多还原
