【摘要】 用三维金相和扫描电镜方法观察并分析了Al-Li合金的断裂类型与微观组织结构的关系,阐明了不同断裂类型的内部联系及其随再结晶过程的变化规律,并从微观结构、能量和几何的观点出发,解释了不同类型断裂的成因、过程和特征.更多还原

【Abstract】 The correlation between the diverse fracture modes and the microstructural va-riation with recrystallization in the Al-Li alloys under heat treatment was observed by means oftriplanar optical and scanning electron microscopy. The growth, propagation and feature of theirfractures were described from the viewpoint of microstructure, energy and geometry.更多还原
