عنوان انگلیسی Investigating the Effect of Ultrasonic Shot Peening Parameters on Metallurgical, Mechanical, and Corrosion Properties of Industrial Parts: A Literature Review
چکیده انگلیسی مقاله Ultrasonic shot peening (USP) is a surface treatment technique widely employed in the automotive, aerospace, and marine industries to enhance the mechanical and metallurgical properties of components. This enhancement is achieved by inducing compressive residual stresses on material surface using spherical shots resonated by a vibrating body, known as the sonotrode. The controllability of USP, with variables such as shot properties (material and size), peening distance, peening duration, peening intensity, peening coverage, and the amplitude of sonotrode vibration, has attracted significant attention from engineers and researchers. To ensure the industrial reliability of USP, a thorough investigation of the process is necessary. This paper aims to review relevant research conducted since 1999 to shed light on the effects of USP on different material properties, including grain size, fatigue strength, corrosion behavior, hardness, and other mechanical, metallurgical, and electrochemical characteristics. A review of the pertinent literature demonstrates that USP can effectively reduce surface grains of materials to a range of 10 to 100 nm while producing surface compressive residual stresses up to 900 MPa. It also significantly enhances fatigue resistance at low strain amplitudes by retarding crack initiation and growth. Although USP increases surface roughness, it can improve corrosion resistance when applied with an optimal peening duration. Additionally, USP can substantially increase hardness, yield strength, tensile strength, and wear resistance.
