摘要：

Aluminum-magnesium alloys are ideal for ship construction; however, these alloys can become sensitized and susceptible to intergranular corrosion when exposed to moderately elevated temperatures. A stabilization treatment has been developed to reverse sensitization and restore corrosion resistance such that in-service plate can be refurbished rather than replaced. This treatment involves a short exposure to a specific elevated temperature range and can be implemented with portable units onboard a ship.
