Inconel 625, nickel based alloy, is found in gas turbine blades, seals, rings, shafts, and turbine disks. Application of Minimum Quantity Lubrication (MQL) in turning process provides as an advanced and green machining concept. The addition of nanoparticle of weight percentage parameters along with machining parameters has a significant influence on the machining characteristics and so, parameter optimization is vital role to obtain the best machining performance. In this study, MQL with CUO, Al2O3 and CNT nanoparticles dispersed vegetable-oil-based cutting fluid is prepared in turning of Inconel 625. The nanofluids are prepared by dispersing 0.1, 0.25, and 0.5 wt% into vegetable oil-based nanofluids to improve the machining characteristics of the Inconel 625. Then Taguchi-Desirability analysis optimization method is used to evaluate the effect of MQL+ machining parameters on the turning characteristic and determine the optimal conditions combination. Results reveals that both surface roughness, Ra and tool wear Vba found to lower value at the optimized cutting parameters of 0.5 (wt%) concentration, velocity 40 m/min and feed rate 0.14 mm/rev and in this case, it is…
 

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

ABSTRACT In the present study the fabrication of joints between the nickel base alloys and steels of various grades have been under taken, joining of these metals has assumed new importance by virtue of their widespread in nuclear and aerospace applications. Such joints provide excellent strength, oxidation and corrosion resistance. This paper deals with the study of weldability, and mechanical properties of weld joints of two different alloys such as nickel based alloy- monel 400 and austenitic stainless steel AISI 321. The joining of the similar and dissimilar metals is carried out by GTAW process by employing two different types of filler rods such as SS321 and ERNiCrMo-3. Mechanical properties such as Ultimate tensile strength, Young’s Modulus are found as per ASTM testing standards, percentage of elongation aslso found to know the joint efficiency and Microhardness survey across the weld joint to estimate the hardness variations at different locations such as Weld zone of the matel, Heat Affected Zone (HAZ), and Base metal. Key Words: GTAW process, UTS, Hardness, Nickel based alloy - monel 400…
