Improvement of Fatigue Strength of Light Metallic Materials by Cavitation Shotless Peening
Cavitation normally causes severe damage in hydraulic machinery such as pumps, valves and so on. However, cavitation impact can be utilized to surface treatment to improve fatigue strength of metallic materials in the same way as shot peening. A peening method using cavitation impact was named as “cavitation shotless peening” or “cavitation peening” as shots are not required. As increase of sur...
متن کاملCharacterization of Surface Modification of 347 Stainless Steel upon Shot Peening
Plastic deformations, such as those obtained by shot peening on specimen surface, are an efficient way to improve the mechanical behavior of metals. Generally, scanning electron microscopy (SEM) and electron backscattered diffraction (EBSD) are commonly used to observe the complex microstructural evolutions, such as grain refinement and phase transformation, induced by the surface treatment. In...
متن کاملEngineering the residual stress state and microstructure of stainless steel with mechanical surface treatments
Four mechanical surface treatments have been considered for the application to austenitic stainless steel structures. Shot peening (SP), laser shock peening (LSP), ultrasonic impact treatment (UIT) and water jet cavitation peening (WJCP), also known as cavitation shotless peening (CSP), have been applied to 8 mm thick Type 304 austenitic stainless steel coupons. This study considers the merits ...
