| Abstract | A study of weld cracking resistance during linear friction joining of a difficult-to-weld nickel-based superalloy was performed by Gleeble thermomechanical simulation coupled with an extensive microstructural analysis. It was found that crack-free welds produced by the supposedly solid-state joining technique of linear friction welding is not due to preclusion of grain boundary liquation as has been commonly assumed and reported. Instead, resistance to cracking can be related to a reduction in liquid stability by the imposed compressive strain during welding. © 2011 Taylor & Francis. |
