“…6, it is seen that the residual compressive stress in the α' increases with decreasing the peening angle. As mentioned in Introduction, several previous researches have reported that the residual compressive stress increases as the peening angle decreases [3,6]. Therefore, the present result shown in Fig.…”

“…Shot-peening can improve fatigue property of metallic materials by inducing residual compressive stress [1][2][3][4][5][6][7]. In addition, since the shot-peening gives large strain around peened surface, microstructure around the peened surface is severely refined and consequently the surface hardness is drastically increased [8][9][10][11][12].…”

“…Because of this, the fatigue property of the Ti-6Al-4V alloy is enhanced by the shot-peening under small peening angle. Also, Ishigami et al have reported that the residual compressive stress in the shot-peened induction-heated steel increases as the peening angle decreases [3]. Therefore, it is possible to control the residual compressive stress around the peened surface by changing the peening angle.…”

Effects of peening direction on the reverse transformation induced by the shot-peening for the Fe-33 mass%Ni alloy with large amount of martensite (α’) are investigated. When the angle between the peened surface and the peening direction (Hereafter, peening angle) is 90 o, the reverse transformation occurs and subsequently martensitic transformation is induced by the shot-peening. On the other hand, in case of the peening angle of 30 o, only reverse transformation occurs. Furthermore, the volume fraction of austenite (γ) in the specimen after the shot-peening increases as the peening angle decreases. This means that the reverse transformation induced by the shot-peening is enhanced by decreasing the peening angle. Moreover, residual compressive stress around the peened surface increases as the peening angle decreases. Since the hydrostatic compressive stress decreases phase transformation temperature, the phase transformation temperature around the peened surface would be decreased by the shot-peening. Therefore, the reverse transformation behavior depending on the peening angle can be explained by the residual compressive stress due to the shot-peening.

“…When metallic materials are subjected to SP, their fatigue and corrosion properties are improved by the residual compressive stress induced by SP. [1][2][3][4][5][6][7][8] Because SP can cause large strain around the peened surface, microstructures around the peened surface are highly refined and the surface hardness is therefore considerably increased. [9][10][11][12][13][14] SP is therefore a surface severe plastic deformation (SPD) process, which can induce residual compressive stress.…”

The crystallographic texture of pure Cu formed by shot peening (SP) and the texture formation process are investigated. When a pure Cu sheet with a β‐fiber texture is subjected to SP, grain refinement occurs and a deformation‐induced layer is formed around the peened surface. The crystal lattice is rotated and a {110} fiber texture, in which the ⟨110⟩ direction is parallel to the plane normal direction of the peened surface, is formed. The intensity of the {110} fiber texture increases with increasing SP duration. The {110} fiber texture is formed by uniaxial compression for face‐centered cubic metals. It is concluded that uniaxial compression is dominant in deformation by SP and a {110} fiber texture is therefore formed. Moreover, using shot‐peened (SPed) specimen with {110} fiber texture, a growth test of graphene is carried out. The SPed specimen is used as a substrate to grow the graphene by the chemical vapor deposition process. Growth of high‐quality graphene on the SPed specimen is obtained compared to unprocessed substrate surface. Therefore, control of the crystallographic texture by SP would be one of important tools for preparing Cu and other catalytic substrate surfaces for high‐quality graphene growth.
