Abstract:

Titanium alloy is a kind of metal material with excellent performance. Due to its low density, high specific strength and corrosion resistance, it is widely used in the field of Marine engineering equipment manufacturing. This paper systematically reviews the current development status of global Marine titanium alloy materials, with a focus on comparing and analyzing the similarities and differences among the three major technical systems of Russia, the United States, and China, and clarifies the weak areas of strength in the material systems of each country and the key breakthrough directions. Based on the functional requirements of Marine equipment, their material properties, research and development status, and engineering application progress are elaborated in detail respectively. At the level of material application technology, this paper focuses on analyzing the technical characteristics of advanced processing techniques such as stamping forming, rolling forming, and structural forming. It also introduces the applicable scenarios and research progress of innovative connection technologies such as narrow gap TIG welding, keyhole tungsten inert gas welding, electron beam welding, and laser welding. Research indicates that in the future, Marine titanium alloy material systems will develop towards high strength and toughness as well as functional integration. The preparation technology will tend towards near-final shape manufacturing and precision manufacturing. The welding process will break through the technical bottleneck of efficient connection of large-thickness components, providing key material support for achieving lightweight, long service life and multi-functionality of Marine equipment.
