钛合金焊缝的EBSD分析
Besd analysis of the melting joints of Ti alloys
【摘要】 采用电子背散射衍射(EBSD)技术,对CO2激光焊接Ti-A l-Nb合金焊缝熔池和热影响区(HAZ)的晶体学取向、晶粒结构及晶界特征进行了测量和分析。此外,EBSD菊池衍射花样质量(IQ)参数表明,经过退火处理后焊缝中的残余应力已基本消除。
【Abstract】 Electron backscatter diffraction(EBSD) technique was performed to measure and analyze the characteristics of the crystallographic orientation,the grain structure and the grain boundary in the melting pool and the hot affect zone(HAZ) of the melting joints of Ti-Al-Nb alloy fabricated by the CO2 laser beam welding technology.Furthermore,the image quality parameters(IQ) of the EBSD Kikuchi bands confirm that the residual stress in the weld joints is released during annealing.
