| Outline of Final Research Achievements |
This investigation focused on the cutting force and the conditions of the surface after cutting in materials with modified surfaces made using friction stir processing. It compared material with modified surface with dispersed particles, and material with a simply modified surface made using friction stir processing.
The results show that the effect of the characteristics of base material is large, and that the machinability of the materials with modified surfaces made using friction stir processing are almost the same when the base material is the same, regardless of whether they are material with a simply modified surface, or a material with a modified surface with dispersed particles.

| Academic Significance and Societal Importance of the Research Achievements |
これまで，検討がほとんど行われていないため，全く明らかとなっていなかった摩擦攪拌プロセス(FSP)を行った材料表面の切削性について，その特徴が明らかにすることができたことは学術的に非常に有意義であると考えられる．また，その結果，産業界においても十分な適用が進んでいないFSPに関して，今後の積極的な利用に対して指針を示すと共に，FSPを初めとする摩擦攪拌技術に関して，基礎的な知見を示すことにより，技術全体に対する理解を促し，基盤的な生産技術の進展に寄与するものと考えられる．
