| 摘 要： | 使用金相显微镜(OM)、扫描电镜(SEM)、电子探针(EPMA)和显微硬度计(MHTM)对爆炸焊接钛-铝复合板的爆炸态、退火态、轧制态界面进行了研究.结果表明:结合面呈波状结合,距爆炸点越远,界面波的波长和波幅越大;周期性轧制裂纹的分布和界面波波形的分布吻合;复合板的界面分布着周期性中间相,中同相由TiAl和TiAl<,2>组成;在450℃×10 h,490℃×3 h的退火条件下,界面钛铝原子相互扩散不明显,更不会生产中间相.由于爆炸硬化和爆炸热效应的共同作用,界面附近钛板和铝板硬度分布规律不同.周期性轧制裂纹是变形时界面的附加拉应力引起的,裂纹源在钛层的最薄处,界面波形参数过大是钛板面出现轧制裂纹的主要原因.爆炸复合时应严格控制波形参数和中间相.

| Abstract: | The interfaces of exploded state,annealed state,rolling state for the titanium-aluminum clad sheet were studied.Optical microscope(OM),scanning electronmicroscope(SEM),electron probe microscope analysis(EPMA) and microhardness tester(MHD) are used.The results show that the interface appears wave.The explosion point is farther,the wavelength and amplitude of the interface waves is greater.The distributions of the periodic rolling crack and interface wave agree well.Periodic mesophases appear in the interface... |
