摘要:
钛及钛合金因优异的综合性能在航空、航天、舰船、化工等行业获得广泛应用,为满足不同的应用需求,近20年我国新型钛合金的研制非常活跃,其中舰船用钛合金是我国钛合金研究和发展的重要研究方向之一。经过近50多年的努力,我国创新研制的不同强度级别船用钛合金已基本形成体系,也制备出这些合金不同规格的管、板、棒、丝材等,已基本能够满足我国工程的需求。本文简要介绍中国创新研制的主要船用钛合金及其应用,如中强高韧Ti75合金、中强高塑Ti31合金、高强高韧Ti-B19合金、中强Ti91和Ti70合金、高强Ti80合金等,同时也简要介绍可能用于海洋工程的其他创新研制的钛合金,如高强(1100Pa)高韧损伤容限型TC21合金、中强(900MPa)高韧损伤容限型TC4-DT合金、强度为1300MPa的Ti-1300、强度为1500MPa的Ti-1500、强度为1600MPa的Ti-1600合金以及中强的低温钛合金CT20等。
Abstract:
Because of their excellent properties, titanium and its alloys have been widely used for aviation, aerospace, shipbuilding, chemical industries and so on. In order to meet the different requirement, new titanium alloy research was very active in China in recent 20 years. Among them, titanium alloy used for shipbuilding is one of the main directions of titanium alloy’s research and development in China. After near 50 years hard working, titanium alloys with different strength scale used for shipbuilding are formed in China, and their different size bars, plates, sheets, rods, wires etal were produced, which basically meet the requirement. This paper reviews the new main titanium alloys used for shipbuilding and their applications, such as Ti75 alloy with middle strength and high toughness, Ti31 alloy with middle strength and high plasticity, Ti-B19 alloy with high strength and toughness, Ti91 and Ti70 with middle strength, Ti80 with high strength and so on. This paper also introduces some new titanium alloys which can be used for marine, such as damage tolerance TC21 alloy with high strength (1100MPa) and toughness, damage tolerance TC4-DT alloy with middle strength (900MPa) and high toughness, Ti-1300 alloy with 1300MPa strength, Ti-1500 alloy with 1500MPa strength, Ti-1600 alloy with 1600MPa strength, CT20 alloy with middle strength and so on.
