Because of rolling contact, galling or breakage in conventional ironing can be prevented and extremely high thickness reduction and mirror finishing of outer surface was demonstrated. Additionally, high pressure can be applied to the radical direction due to the high rigidity of the axis support cone. This stress state causes radical material flow easily and the possibility of giving a certain feature on tube surface by PCR was reported. In this paper, by replacing a die with the flange having a concavity, flow joining of tube and flange by PCR was discussed. Material flow into the concavity was investigated and it was found that filling-up volume was increased with increasing the material on the concavity, though it was not affected by the position of concavity. Joining strength to the axial direction was estimated with a simple model and required filling depth into the concavity was clarified. Joined component was subjected to the separation test and measured strength was in good agreement with calculated value.}, pages = {1891--1896}, title = {PCR加工による円管とフランジの塑性流動締結}, volume = {68}, year = {2002} }
