Effect of intermetallics of 2219-T87 aluminium alloy on exposure to aggressive media

The effect of precipitating agent Al2Cu intermetallic particles of high strength 2219-T87 aluminum alloy plate (AA2219-T87) used in cryogenic propellant tank for space applications has been investigated on exposure to aggressive media like unsterile natural seawater and 0.6 M NaCl solution. The corr...
