started to trench in the periphery of Al2CuMg particles at the early stage of dealloying. Development of trenching in Al-Cu-Fe-Mn-(Si) particle’s periphery was not uniform and took longer time to initiate... dissolution; dealloying; trenching 1 Introduction High-strength aluminium alloys such as AA2024-T3 have been widely used for aerospace applications because of their light mass, high strength and damage......
trenching. Small pores in the films are induced by the dissolution of precipitates in grain or subgrain boundaries. The film surface of recrystallized grain bodies is smooth and homogeneous.关键词:......
