Characterization 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 کاملCorrosion Properties of 34CrMo4 Steel Modified by Shot Peening
A nanocrystalline layer was prepared on the surface of 34CrMo4 steel by time controlling shot peening (SP, i.e., 1, 5, 10, and 20 minutes). Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) analysis, and transmission electron microscope (TEM) were applied to analyze the surface, cross-sections, and grain size of the specimens before and after SP. The electrochemical c...
متن کاملRegression analysis of shot peening process for performance characteristics of AISI 304 austenitic stainless steel
The surface fibers of the material are yielded in tension by the impact of shots in shot peening process. Below the surface fiber an even thin skin surface layer of material is deformed and this layer is highly stressed in compression. It results in the improvement of surface and mechanical properties of the material. Regression analysis is the statistical modeling technique, and it is suitable...
متن کاملEnhanced pool-boiling heat transfer and critical heat flux on femtosecond laser processed stainless steel surfaces
In this paper, we present an experimental investigation of pool boiling heat transfer on multiscale (micro/ nano) functionalized metallic surfaces. Heat transfer enhancement in metallic surfaces is very important for large scale high heat flux applications like in the nuclear power industry. The multiscale structures were fabricated via a femtosecond laser surface process (FLSP) technique, whic...
متن کاملShot peening effects on corrosion behavior of Hydroxyapatite coated AISI
The effect of several Almen intensities of shot peening on the corrosion behavior, surface roughness, micro hardness profiles, and residual stresses of stainless steel AISI 316 L were investigated. Hydroxyapatite coating (HA) were applied to shot peened materials to improve their corrosion resistance. The corrosion behaviour were studied using potentiodynamic polarization. The electrochemical t...
