چکیده مقاله
Electron beam welding was applied to join dissimilar Ti55/TA15 high temperature titanium alloys Defect free joints were obtained Microstructure observation via optical and electron microscopes showed that FZ consisted of martensite α΄ and acicular α The HAZ of both Ti55 and TA15 sides consisted of two regions; LT HAZ consisted of primary α, secondary α and prior β and HT HAZ mainly composed of martensite α΄ and acicular α In addition, a characteristic asymmetrical microhardness profile was observed in dissimilar welded joints lower hardness of fusion zone rather than HAZ of both Ti55 and TA15 alloys Room temperature tensile test results represented slightly weakness of weld metal compared to the Ti55 and TA15 alloys, however, good strength of welded joint at high temperature test results was achieved
