Abstract:

Rolling strategy is the key problem in the designation of ring rolling technology, especially for the difficult to deformation materials, such as titanium alloy and superalloy, and it is also the crucial factor that influences the microstructure and dimensional accuracy of the ring. In this paper, three types of rolling strategies are designed and the corresponding radial/axial ring rolling experiments are performed employing these rolling strategies on GH4169 billets with the same dimensions.

Key words: GH4169 , alloy,  , rectangle , crosssection , ring,  , rolling , strategy,  , radial/axial , ring , rolling
