“…The wear resistance and fatigue performance are two of major concerns in those applications [2]. For conventional engineering alloys such as stainless steels and titanium alloys, several surface treatment techniques such as shot peening have been widely used to improve those two properties in metallic components of bulk materials [3][4][5]. For SMAs, besides the improvement of wear and fatigue performance, the shape memory characteristics of the materials often require being preserved in their applications.…”

a b s t r a c tIn this study, microstructure and mechanical properties of an austenite NiTi alloy treated with laser shock peening (LSP) was investigated. It was found that the thickness of shock affected layer is about 250-300 μm. The surface hardness of the specimen is increased by approximately 10% after LSP. Laser induced shock introduces slightly residual compressive stress in the peened specimen. The superleastic stress-strain curves of the fully LSP processed NiTi material show no change in phase transition stress, about 100 MPa decrease in martensite yield stress, and a loss of maximum transition strain about 12% after LSP. The ultrahigh-strain-rate plastic deformation by LSP results in dislocation substructure and amorphization underneath the surface which are responsible for the hardness increase and superelastic strain loss.

“…Second, the size/diameter of shots should be discrete values between 0.0450mm to 4.75mm [23] and the values are set in SAE J444 [23]. Note that most researchers such as Xie, et al [24] set the values according to this range while 38mm was used for 3D by Klemenza, et al [25]. Third, values of incidence angle could be set at a range of 45º to 90º [26] with respect to the target surface for it is energy-saving and also consistent with reality operation.…”

Abstract. This article provides a broad and extensive literature survey on optimisation of shot peening process that have been developed and applied in the past decades and summarises the knowledge that has been gained and then points out the shortages of the important investigations in optimisation of shot peening process. On this basis, optimisation function is formulated and genetic algorithm is chosen to conduct the optimisation. This optimisation screens out the influential parameters and provides the weights of different parameters in terms of their influence of shot peening outputs.

“…Also other research from recent years [8,14,20], presents the results of the numerical FEM simulations of shot peening, including vibratory shot peening. In these works, the authors have focused primarily on the results obtained after shot peening, such as plastic deformations of workpieces, the theoretical amount of surface roughness after the strike with a strong of beads and residual stresses in the surface layer, without conducting the kinematic and dynamic analysis of the peening elements.…”

ABSTRACT:The paper presents the results of numerical calculations, with the finite element method in the ABAQUS program environment, of the vibratory shot peening process with loose peening elements. The behaviour of shot peening elements was analysed in the kinematic aspect. The impact of the initial deployment of vibratory shot peening elements on their behaviour during processing was investigated, including the displacement, velocity, acceleration and the number of collisions. The way of determining the effectiveness of the processing with the vibratory shot peening was illustrated.
