1. アルミニウム合金に対し，ショットを自由落下するだけのショットピーニング加工 NSTL国家科技图书文献中心

小林祐次 - 《熱処理》 - 2025,65(1) - 11～14 - 共4页

摘要：ショットピーニングは，冷間加工法の一種であり，直径0．05～1mm程度のショットと呼ばれる | 金属あるいは非金属の球を対象となる金属の表面に高速で打ちつけることにより，硬さの向上や圧縮残留応力の | 付与といったピーニング作用を得る手法である（1）。ショットが金属表面に衝突すると，その表面は降伏点を | 越えて塑性変形し，くぼみを形成する（囲1）。塑性変形領域の直下および，その周辺は変形に抗する応力状態と | なるため，圧縮の残留応力として残る。
