Patent number: 9162318Abstract: A friction stir processing apparatus comprises a tool, a processing head retaining the tool, a support table retaining the workpiece, and a cylinder unit biasing the support table toward the tool. The tool having a probe projecting from a shoulder surface, for performing friction stir processing on a workpiece made of a metal material. The processing head is pressing the tool against the workpiece so as to relatively shift the tool in a processing direction. The friction stir processing apparatus comprises load control means for controlling to constantly keep the bias force of the cylinder unit so as to constantly keep pressurizing force of the tool pressing the workpiece. It is thus possible to perform friction stir processing with excellent quality even when the workpiece has a different thickness or is made of a different material.Type: GrantFiled: March 27, 2012Date of Patent: October 20, 2015Assignee: ISEL CO., LTDInventors: Sachio Oki, Kiichi Kakei, Tomotake Hirata, Takayuki Takasugi, Yasuyuki Kaneno, Noboru Mochizuki, Takanori Uchida

Patent number: 8857695Abstract: A friction stir processing tool is formed from a Ni-based dual multi-phase intermetallic compound alloy containing rhenium(Re). The Ni-based dual multi-phase intermetallic compound alloy is preferably formed by casting, while gradually cooling, a melt containing all the components of the composition and is preferably heat treated after casting. Moreover, in a method for friction stir processing, a work is softened by friction heat generated when the friction stir processing tool, while rotating, is pressed against the work to be processed. The friction stir processing tool includes the Ni-based dual multi-phase intermetallic compound alloy, and therefore further high hardness is exhibited to improve abrasion resistance, so that even a long period of friction stir processing can be endured.Type: GrantFiled: March 27, 2012Date of Patent: October 14, 2014Assignees: Osaka Prefecture University Public Corporation, Kinki University, Isel Co., LtdInventors: Takayuki Takasugi, Yasuyuki Kaneno, Sachio Oki, Tomotake Hirata, Noboru Mochizuki
