图9. 代表性的TEM与APT照片展示了Al-Cu-Mg-Ag基合金中Ω相的形貌与成分，及其适应“短期”服役但不耐“长期-高温”耦合服役环境的力学性能特点[152~155]

Fig.9. Representative TEM (a)[152] and APT (b)[153] images showing the morphology and chemical composition of Ω phase in Al-Cu-Mg-Ag-based alloys, and curves indicating this system has great high-temperature resistance within short period while suffers from rapid softening at high temperature (c)[155] and long duration (t—time) (d)[154]
