weak interface

The decohesion of the weak interface between particle and matrix may be considered as the origin of toughening.

认为颗粒与基体间弱界面的解聚是熔融石英颗粒复合材料韧化的原因。

The inherent relationship between interface morphology and separation properties indicated that the weak interaction between organic and inorganic components could lead to more ideal interface morphology.

界面形态与宏观分离性能的内在关系表明，有机和无机成分之间的弱相互作用力有利于形成较理想的界面形态。

The cracks first propagate in the direction dictated by the weak interface of Be and Al, then grow towards in depth. The cracks may propagate along Be basal slip plane parallel to the loading direction in the material.

裂纹主要沿Al和Be结合强度较弱的表面路径扩展，随后沿纵深方向扩展，在材料内部裂纹扩展方向会变为与加载方向平行的Be基滑移面方向。

During the welding process of titanium alloy and aluminum alloy, it is easy to form many kinds of brittle intermetallic compounds at the interface of Ti/ Al dissimilar alloys. Those compounds weak the bonding strength of Ti/ Al joints.

钛合金和铝合金的焊接过程中，在Ti合金/Al合金界面处极易生成各种脆性的金属间化合物，制约着接头的结合性能。
