Verification of Pilger Mill Performance

Sep 24, 2018 Pilgering can produce high levels of cold deformation in hard-to-process ODS, as well as produce advantageous textures in the material. The pilgering process allows for higher reductions of area (ROA) in a single pass than the cold draw process. This higher ROA potential is a result of the compressive nature of pilgering.
