摘　　要：对作为载人深潜器耐压球壳用新型Ti-6321钛合金大规格锻板的工程化制备及其显微组织和力学性能进行研究。结果表明:该锻板在不同厚度和不同取向的室温拉伸性能和显微组织的均匀性良好,没有明显的各向异性。锻板具有优良的冲击韧性、断裂韧性、弹性模量、冷弯和500℃高温拉伸性能,是一种理想的海洋和舰船用钛合金结构材料。The industrial manufacturing, microstructure and properties of Ti-6321 new titanium alloy big size forged plate used for pressure spherical hull of manned submersible were investigated. The results show that the room temperature tensile property and microstructure of the forged plate in different positions and directions have good homogeneous, and the anisotropy is not obvious. The plate is perfect structural material for ocean and ship, which has excellent fracture toughness, elasticity modulus, cold bending and 500℃ high temperature tensile properties.
