深海装备耐压结构用钛合金材料应用研究
Application of Titanium Alloy Materials for the Pressure-Resistant Structure of Deep Diving Equipment
本文概述了国内外钛合金深海装备的发展现状，针对深海服役环境特点对耐压结构用钛合金材料的性能要求进行了分析，介绍了典型装备耐压结构钛合金材料研究应用中出现的应力腐蚀和蠕变等技术问题，提出需要针对钛合金材料长期服役时存在的组织演变和性能衰减、冲击环境下的动态响应等基础科学问题开展研究，重点梳理工程应用中的大规格材料、应用评价和高效建造等关键技术。文章建议针对深海领域钛合金装备的迫切需求，进一步加大钛合金材料基础研究和工程化应用力度，推动创新应用，践行海洋强国战略。
The development of titanium alloy deep-diving equipment is first summarized, and the desired properties of titanium alloy materials are then analyzed considering the characteristics of the deep-sea service conditions. Technical challenges faced by the application of deep-diving equipment are also introduced, including stress corrosion, compressive creep, microstructure evolution, property attenuation, and dynamic response under impact loading. Finally, key technologies in engineering application are summarized, such as large-size materials, application evaluation, and efficient construction. To satisfy the urgent demand for titanium alloy equipment in the deep-diving field, we propose to further increase basic research and engineering application of titanium alloy materials, and promote innovative application.
