Thermal Stability of Surface Layer Microstructures of Commercially Pure Titanium Treated by High Energy Shot Peening ZHANG Yu-juan1,REN Rui-ming1,CHEN Chun-huan1 (1.Dalian Jiaotong University, Dalian 116028, China) 摘要:Commercially pure titanium was treated by high energy shot peening, and annealed at a series of temperatures. The surface layers are characterized by means of scan electronic......
Academy of Sciences, Shenyang 110016, China) Abstract: A nanostructured surface layer was fabricated on 1420 aluminum alloy by high-energy shot peening. Microstructures were characterized by X-ray... of the sample peened for 30min. The results show that a nanocrystalline layer about 20μm in thickness is formed on the surface of the sample after high-energy shot peening, in which the grain size......
Effect of shot peening and grit blasting on surface integrity: Influence on residual stresses K.TOSHA1, LU Jian2 1. Department of Mechanical Engineering, Meiji University, 1-1-1...; the critical thickness of shot peening is about 50% thicker than that of grit blasting; the high compressive stresses induced by blasting are owing to the wrought or peening effect. Key words: shot......
University摘 要:A new technology-rotationally accelerated shot peening(RASP), was developed to prepare gradient structured materials. By using centrifugal acceleration principle and large steel balls, the RASP technology can produce much higher impact energy compared to conventional shot peening. As a proof-of-concept demonstration, the RASP was utilized......
