Comprehensive characterization of a material produced by a laser directed energy deposition setup, detailing its microstructural features and chemical composition through optical, SEM, and EDS analysis. The included particle size distribution graph provides critical insights into the feedstock powder's influence on the final properties.
In this research, the influence of process parameters in Wire Arc Additive Manufacturing (WAAM) of Stainless Steel 316L as the filler wire and mild steel as the substrate was analysed. The deposition was accomplished utilising the Cold Metal Transfer (CMT) technique. Single-pass beads are more beneficial for remanufacturing and mending.
The majority of the quality of cladding for additive manufacturing is determined by bead geometry. Therefore, an optimal range of bead characteristics is necessary to achieve the requisite mechanical qualities.
To assess the impacts of wire feed speed, travel speed, and gas flow rate on bead properties, response surface methods was used. The impact of wire feed speed, travel speed, and gas flow rate on bead width and height was investigated during the optimization process.
In this work, friction stir processing was successfully done on the ZE41 Mg alloy reinforced with different proportions of Al2O3 (with average particle size of 17 µm) at 1150 rpm tool rotational speed and 30 mm/min tool traverse speed with a single FSP pass.
This work examines the effect of FSP and Al2O3 particles on the microstructure and micro-hardness of ZE41-Al2O3 composite produced by FSP. The mechanical and microstructural behavior was investigated by microstructural study in detail using optical microscope and Field Emission Scanning Electron Microscope (FESEM) with grain size measurement and Microhardness testing.
