研究用原始Ti－6A1－2Cr－2Mo－25n－2Z对合金是含几刀和外两种硅含量的原锻件，并经过三重热处理：川1000℃/h，风冷；（2）925℃（a＋相区）/1h,风冷；（3）540℃时效8h，空冷．以原锻件上切取数个样品，封于真空充花石英管中，作进一步热处理．部分样品在600℃一650℃处理6h
The original Ti-6A1-2Cr-2Mo-25n-2Z alloy was studied as a primary forging material with several knives and two kinds of silicon contents and subjected to triple heat treatment: 1000 ℃ / h, air cooling; (2) 925 ℃ a + phase area) / 1h, air cooling; (3) 540 ℃ aging 8h, air cooling. Several samples were taken from the original forgings and sealed in a vacuum-filled quartz tube for further heat treatment. Some samples were processed at 600 ℃ to 650 ℃ for 6h
