The phase composition and phaseboundaries were determined by X-ray diffraction.
用X射线衍射确定了相组成与相界。

When the crack is small, the fatigue crack growth is obviously influenced by microstructure features and multiple phaseboundaries.
在裂纹较小阶段，疲劳小裂纹的扩展受显微组织与多相界的影响。

According to the recent studies on interfaces in crystals, it is evident that most grain boundaries and phaseboundaries have two dimensional periodic structures.
