Description
Claims (4)
- 軽合金材料を用いて鋳造法又は鍛造法によって成形して成形品を得た後に、その成形品の表面に閉空間を形成し、その閉空間に比重が2以上で径がφ5mm以上の球状体又は多面体を少なくとも含む加工材を投入し、その加工材を投入した前記閉空間が表面に形成された前記成形品を上下方向に揺動をさせて、前記加工材を前記成形品の表面に衝突をさせる、という工程を経て製造された、
表面からの深さが500μm以上6000μm以下の部分に、圧縮された応力が残留している軽合金製品。 - 表面からの深さが1000μmの部分における前記応力が、100MPa以上である請求項1に記載の軽合金製品。
- 表面からの深さが1μm以上50μm以下の部分に、表面側と内部側とを区切る断層が形成されている請求項1又は2に記載の軽合金製品。
- 車両用ホイールである請求項1〜3の何れか一項に記載の軽合金製品。
