Mechanical Properties of Similar and Dissimilar Metals of Monel 400 and SS 321 by Using Gas Tungsten Arc Welding (GTAW) Process

This study is aimed to investigate laser irradiation effects on the surface, structural, and mechanical properties of iron samples. The prepared samples have been treated for multiple exposure times using continuous-wave diode laser with a wavelength of 532 nm in a laboratory environment. The structural as well as surface modifications of laser exposed targets are explored via scanning electron microscope and X-ray diffractometer. The SEM analysis revealed micrometer grain size, exfoliational sputtering, and crater formation, while XRD patterns were used to investigate d-spacing, and grain size of laser exposed samples. The mechanical characteristics of laser-ablated materials were examined using a micro Vickers hardness-tester, and microhardness has been explored as a function of increasing laser exposure time. It has been observed that grain size reduces while hardness of polycrystalline iron increases with increase in exposure time.

The impact of high-intensity visible radiation on the morphological, structural, and mechanical characteristics of pure lead has been examined via the irradiation of a continuous-wave diode laser on its samples. SEM and X-ray diffractometers were used to analyze the surface and structural morphology of the irradiated samples. The appearance of the burning effects, redeposition of material, and melt pools were checked after the irradiations in the SEM analysis. On the other hand, through the diffractometric X-ray analysis, the targeted sample’s d-spacing, grain size, and dislocation line density were resolved. To understand the mechanical characteristics of lead, the change in hardness of the materials was tested as a function of exposure duration using the micro-Vickers hardness tester, and the resulting outcomes were compared with those of unirradiated ones. The hardness of lead is enhanced as the exposure time increases, and this is accompanied by a continuous reduction of the grain size.
