Aluminum alloys in marine construction: characteristics, application, and problems from a fabrication viewpoint

摘要

Aluminum alloys (AAs) of 5xxx and 6xxx are employed in marine construction and shipbuilding, particularly in the construction of hulls, superstructures, and deck panels of ships due to their high strength-to-weight ratios and corrosion resistance characteristics. Fabrication of these structures often poses serious threats during the joining (welding) as these alloys exhibit a vast difference in chemical and mechanical properties. Moreover, corrosion of these alloys in marine atmosphere is also a serious issue. The objective of this paper is to present a review on the use of potential AAs for marine applications. Furthermore, serious challenges faced during the fabrication of these alloys are also highlighted in this article. Thus, this article will be of great help to researchers and academicians in finding answers to the problems faced during marine vehicle fabrication. The important characteristics, application, and problems faced while fabricating these alloys are collectively addressed in the present manuscript.
