Equal channel angular extrusion of difficult-to-work alloys |
摘要 |
A method is described for producing homogeneous wrought microstructure during equal channel angular extrusion of difficult-to-work high temperature alloys that exhibit a high degree of flow softening at hot-working temperatures, wherein flow non-uniformities are minimized by imparting an increment of initial upset deformation to an alloy immediately preceding shear flow through the deformation zone.
