“…18 The parametric optimization of rotary friction welded UNS S31803 rod joints was studied by comparing GRA and Taguchi method showed that heating time and upsetting time had an effective influence on response. 19 The joint strength was shown to decrease as the friction time increased, whereas the hardness of the joint rose. 20 Friction stir welding of DSS plates at speeds of 50, 100, 150, and 200 mm/min resulted in sound weld joints, however, at 250 mm/min, a groove-like defect caused by insufficient heat input was discovered.…”

The aim of this work was to systematically find the optimum parameter combination using the response surface methodology (RSM) technique for welding of UNS S31803 tubes and to find the effect of parameters on mechanical and metallurgical properties. In the present work, the experimental investigations of friction-welded UNS S31803 tube joints are discussed in detail with characterization, radiography, and corrosion studies. The most important parameter that has the greatest impact on the tensile strength of the joints is the upset pressure, which is followed by heating time, heating pressure, and upset time. As the upset pressure and time increased, the joint strength also increased. The radiographic evaluation of the weldments revealed no significant flaws at the weld contact. In comparison to the parent metal zone, the microstructure indicated coarse grain structure in the weld metal zone, with grain orientation changing with upset time. For the optimal parameter combination, the austenite phase is primarily spread in the weld metal zone. In comparison to the partially deformed zone and the parent metal zone, the weld zone had lower hardness values. In the high strength and optimum parameter joints, fractography investigation revealed ductile failure.

“…e F value is utilized to trail the importance of an element in the ANOVA (Table 8) by set side-by-side model variance along with the variance of residual (derived by splitting the model's mean square through the mean square of residue) [31][32][33]. If the difference in the value is close in proximity to one another, the ratio obtained would be close to one, and any of the factors will be less likely to have a substantial impact on the response.…”

The AA6063 aluminium alloy has gained widespread use in manufacturing the light-weighted structures which requires a high strength to weight ratio, and it possesses an excellent corrosive resistance in T6 heat-treated (solution heat treated and artificially aged) condition. The process of friction stir welding (FSW) is an emerging joining process of solid state that does not melt and recast the material being welded, as opposed in various other fusion welding processes, which are extensively utilized for combining the structural alloys of aluminium. The process of connecting separate components with external heat has resulted in induced stress on metals. The stir welding using friction was introduced in order to reduce the formation in residual stress during the joining process. The aluminium alloy AA6063 plates were fused utilising the friction stir welding procedure in this study. The studies were carried out using various combinations of speed in rotary condition, speed in transverse condition, and stress in axial condition. The generated joints that are welded was analysed mechanically and microstructurally. The maximum hardness of the mechanical joints produced is 93.25 HV, and the maximum tensile strength is 286.15 N/mm2. According to the results of the response surface analysis, transverse and rotary velocities possess a notable impact in hardness and durability, respectively.

“…Higher nitrogen content and fine-grained structure of duplex stainless steel (DSS) are attracting many applications. Combination of high strength and higher corrosion resistance in the critical environment is showing DSS to be a great option for austenitic stainless steel (ASS) [1]. A lower percentage of nickel due to the addition of nitrogen is responsible for the lower cost of DSS without compromising mechanical and microstructural properties.…”

Dual-phase structure with 1:1 ratio of austenite and ferrite is termed as "Duplex". Lower cost of duplex stainless steel (DSS) with a combination of good strength and corrosion resistance in a critical environment is captivating many applications. This research work highlights the experimental study of effect of cutting parameters such as cutting speed, feed rate, AlTiN and AlTiCrN-coated tools on response parameters, viz. tool life, surface roughness and cutting forces. Multi-objective optimization using grey relation analysis (GRA) was done to optimize quality response characteristics. High-power impulse magnetron sputtering was used to deposit AlTiN and AlTiCrN coatings on tungsten carbide substrate. Performance measures such as tool life, surface roughness and cutting forces were measured during dry turning of DSS2205 and optimized using Taguchi's GRA technique. AlTiCrN-coated tools exhibited the best results followed by AlTiN-coated tools and uncoated tools. Tool life achieved with AlTiCrN-coated tools is 7 times more than uncoated tools, in which surface roughness was found to be reduced by 67% and cutting forces by 25%. Weighted GRG grade shows that for all the tools used, a cutting speed of 100 m/ min and feed rate of 0.12 mm/rev provided optimum results for response parameters. For change in weightage to response characteristics, different optimum conditions were found for all the tools used. AlTiCrN-coated tool with 100 m/min cutting speed and 0.12 mm/rev feed rate performed better with the highest tool life, the least surface roughness and cutting forces. The results were confirmed by S/N ratio plots.
