| Abstract: | The effect of Al in Ti-microalloyed welding wire on microstructure and toughness of deposited metals is studied.The results show that the deposited metal toughness worsens with increasing Al in wire' The mechanism of Al is as follows:(1) Al makes oxygen content in deposited metal increase.(2)Al restrains the formation of Ti-rich oxide inclusion, which causes granular bainite microstructure in deposited metal.(3)The content of solute Ti in deposited metal increases with Al content in welding wire,as a result,a part of carbonrich constitution in deposited metal is in the form of twin martensite. |
