1.概述Ti-5Al-5Mo-5V-1Cr-1Fe(BT22)钛合金是原苏联航空材料研究院(BNAM)于1974年研制成功的。BT22钛合金是一种高强度合金,在退火或锻造状态下强度极限可达1080MPa,并具有满意的延伸率、断面收缩率和冲击韧性,在强化热处理状态其强度高
1. Overview Ti-5Al-5Mo-5V-1Cr-1Fe (BT22) titanium alloy was developed by the former Soviet Aviation Materials Institute (BNAM) in 1974. BT22 titanium alloy is a high-strength alloy with an ultimate strength of up to 1080 MPa in an as-annealed or forged condition with satisfactory elongation, reduction in area and impact toughness, high strength in the heat-strengthened state
