摘要
研究了Al-Li系8090合金在时效过程中的显微组织与拉伸断裂行为。结果发现，时效造成的沿晶析出及伴随产生的沉淀物无析出带是促使合金发生沿晶开裂的主要因素。
The microstructure and tensile fracture behavior of Al-Li-Mg-Zr alloy 8090 after ageing were studied in this paper. The results show that the precipitates on the grain boundaries and precipitate free zone (PFZ) were the main factor to enhance the intergranular crack of the alloy.
