摘要
BT22钛合金是退火状态下强度最高的高强度结构钛合金,不受淬透性的限制,特别适合制造大锻件,在航空领域应用广泛。本文对BT22钛合金的热处理、性能和组织、选材应用等几个方面的研究现状进行了综合评述。
BT22 is adapted for manufacture of large forgings as its highest strength after heat treatment in the high strength titanium alloys, which is widely used in aviation industry. The statement of heat treatment, mechanical properties and applications of BT22 are analyzed in this paper.
