Abstract
A method for producing the metal cylinder material according to the present disclosure includes: a process A of forming a slitted cylinder-shaped body including at least one slit extending from one end face to the other end face of a cylinder barrel portion consisting of at least one metal plate material; a process B of forming a filler-equipped cylinder-shaped body including a filling portion obtained by filling the slit with a filler for the filler to be filled throughout the slit in a length direction of the slit; and a process C of, by inserting at least a probe of a friction stir rotation tool including the probe at least into the filling portion and executing FSP, reforming at least the filling portion of the filler-equipped cylinder-shaped body to obtain the metal cylinder material including an FSP portion.
