Ti811 titanium alloy
Ti811 alloy is a titanium alloy developed in the 1950s in the United States, which can be used for a long time at 450℃. Its nominal composition is Ti8Al1Mo1V (Chinese brand is TA11). Its phase transition point is 1040℃. This alloy is suitable for use asan aeroengine compressor blade material. The mechanical properties of TA11 alloy are shown in Table 1-4, and the common microstructures of TA11 alloy are shown in Figure 1-19~Figure 1-30.
