Abstract:
Based on the uniformity of grains, the development of main plastic forming technologies of GH4169 alloy, including extrusion, die forging and rolling, are introduced in this paper. The problems existed in the forming process and corresponding solutions are summarized. At present, the plastic forming technologies of GH4169 alloy have been considerably developed. It is developing in a precision forming direction. Meanwhile, there are still some problems needed to be further analyzed, like the residual stress distribution after cold or hot deformation and its effect on the precision of components when it is released gradually.
