一种高性能钛合金
摘要：
本发明涉及一种高性能钛合金新材料，该合金的化学成分及质量百分比为：Al：3％～7％；Mo：1％～6％；V：0.5％～6％；Sn：1％～4％；Zr：1％～4％；Cr：0.5％～3％；Nb：0.5％～3％；Si：0.01％～0.3％；Ti为余量。该高性能钛合金的综合性能非常好，在国内外处于领先地位。突破点在于：在强度和塑性保持在最高水平时，大幅提高钛合金的断裂韧度，提高钛合金零部件的使用性能，使我国飞机综合性能得到进一步提高。
摘要（英）：

The invention relates to a Ti alloy new material with high performance. The alloy has the chemical components by weight percent: 3-7 percent of Al, 1-6 percent of Mo, 0.5-6 percent of V, 1-4 percent of Sn, 1-4 percent of Zr, 0.5-3 percent of Cr, 0.5-3 percent of Nb, 0.01-0.3 percent of Si, and the balance of Ti. The high performance Ti alloy has favorable comprehensive performance, is in the leadin the worldwide and has the breakthrough points that the strength and the plasticity are kept at the highest level, the fracture toughness of the Ti alloy are greatly enhanced, the use performance ofTi alloy parts is improved, and the comprehensive performance of planes of the country is further improved.
