Microstructure and electrochemical behaviour of laser clad stainless steel 410 substrate with stainless steel 420 particles Jeyaprakash Natarajan, Bhuvanesh Kumar Manickam, Che-Hua Yang, Susila Periyasamy International Journal of Materials Research, 2023 Stainless steel (SS) 410 is widely used in many engineering applications such as turbines, nuclear reactor components and seamless pipes due to its superior mechanical properties i.e., high mechanical strength, creep resistance and ductility. Corrosion resistance is an important property which is required for these components to reduce the material degradation from the surface. In the present study, an investigation has been made to enhance the electrochemical behavior of SS410 by depositing SS420 particles using the laser cladding technique. The hardness measured through nano-indentation tests and microstructure of the resulting surface were analysed. Also, electrochemical studies were performed on laser clad specimens with different durations such as 0 h, 8 h, 14 h and 36 h. The improvements in corrosion resistance were analysed using polarization curves and electrochemical impedance spectroscopy (EIS). Further, the morphology and roughness of the corroded surface were analysed. The results showed that a closely packed acicular structure was formed through cladding, which improved the nanohardness compared to the base material. In addition, the clad specimen with 14 h test duration exhibited excellent corrosion resistance amongst the other specimens. The morphological analysis of the corroded specimen revealed the formation of oxides which is indentified to be a major reason for improved corrosion resistance.
The microstructure transformations and deformation behavior of Al-4Mg-0.2Zr alloy rolled at ambient and cryogenic temperatures C Chinthanai Selvan, C Sathiya Narayanan, S Vigneshwaran, R Narayanasamy, P Susila Materials Research Express, 2019 Al-4Mg-0.2Zr alloy samples were rolled at ambient (AT) and cryogenic (CT) temperatures with two distinct thickness reductions and the results were evaluated with regard to the mechanical strength, x-ray diffraction (XRD), microstructural characterization and texture. The strength and hardness were found to be increased after a 50% rolling reduction at both temperatures. Conversely, a subsequent reduction to 75% resulted in the decrement of mechanical properties and indicated the onset of work softening. XRD studies confirmed the reduction of dislocation density at higher rolling reductions. The structural evolution analysis by transmission electron microscopy (TEM) pointed out the occurrence of work softening with the annihilation of dislocation cores and also the polygonization of cell structures into fine sub-grains by higher rolling reductions at both the temperatures. Electron backscattered diffraction (EBSD) analysis confirmed that the grain refinement was significantly high at lower reductions and also revealed that the formation of the subgrain structures was high when rolled at CT at higher reductions. Hence, it was evident that both hardening and softening were attained in successive strain stages at both the temperatures. In terms of strength, the alloy rolled at CT was found dominant over its counterpart rolled at AT on both the reduction levels. Finally, cryo-rolling prevailed the capability of sustaining the high strain induced softening to some extent with better dislocation stability and enhanced mechanical properties over the ambient temperature rolling.
