2023-01-5149

2/23/2024

Inconel 718 is a nickel-rich superalloy that can function in cryogenic to high-temperature applications. It has excellent mechanical and corrosion-resistant properties. This research focuses on developing Cu and Cu–alloy–tungsten disulfide (WS2) tools developed through a stir casting route, and the machining behaviour of Inconel 718 alloy in the EDM Process is investigated. The influence of output responses of Removal rate of material (RRM), surface roughness (SR), and tool wear loss rate (TWR) on input constraints pulse time-on, peak discharge current, and type of tool. The optimal parameters are studied with the aid of the Response Surface Methodology (RSM) and Analysis of Variance (ANOVA) combination, in response to maximize and decrease the RRM, TWR, and SR, respectively. It is found that using the Cu-WS2 tool provides an optimum finding with a peak discharge current of 18 Amps, and pulse on time of 8 μs yields the best value for RRM, TWR, and SR. In addition, a three-dimensional contour plot between the tool type and process parameter's input and output values was obtained. Finally, the confirmation test was conducted, and then it was compared with the experimental and expected outcome. The optimal solution's minimum deviation reflects the effectiveness of the optimized model.

Investigations on advanced Joining Method for Inconel 718 and SS304 Dissimilar Joints

2022-28-0345

10/5/2022

Modern automobile applications such as petrol, diesel, and gaseous fuel injection system use dissimilar Inconel 718 (IN718) and Stainless Steel 304 (SS 304) joints. IN 718 is a precipitation-hardened austenitic nickel-based superalloy with exceptional qualities such as high strength, resistance to corrosion, greater toughness, as well as resistance to thermal induced fatigue at elevated temperatures (between 150 and 1500oC), while SS 304 is a T 300 Series austenitic stainless steel alloy that can be used successfully in wide range of applications due to greater resistance to corrosion, good high and low temperature strength and ductility with excellent weld ability and formability. To get a better understanding of the mechanical characteristics of these heterogeneous weldments, these alloy joints were created using laser beam welding, one of the most modern joining techniques for high-strength materials. Laser Beam Welding (LBW) has received significant attention in recent decades owing to a number of benefits it offers over traditional joining techniques, including improved physical and mechanical characteristics with fewer errors and a fast process that consumes less energy, making it more economical. In the present investigation, crack-free deep penetrating joints of 1mm thickness were created using laser beam welding. Tensile and hardness measurements were taken on the joint. The joint had poor strength and failed at the Fusion Zone (FZ). The mechanical characteristics of deeply penetrated laser welded dissimilar weldments made of Inconel 718, a nickel-based superalloy, and SS 304 are investigated in this article. Mechanical properties were determined at room temperature using the Vickers hardness and tensile tests. The experimental findings indicated that the tensile samples of the dissimilar welded joints was ruptured at the fusion zone and showing a clear ductile mode of fracture.

Full-Range Fatigue Life Prediction of Metallic Materials Using Tanaka-Mura-Wu Model

05-15-02-0010

12/27/2021

In this research, the recently developed Tanaka-Mura-Wu (TMW) model is applied to common engineering materials including Ni-base superalloys Haynes 282 and Inconel 617, aluminum alloys 7075-T6 and 2024-T3, alloy steels SAE 4340 and SAE 1020, and titanium alloy Ti-6Al-4V, as well as a high-entropy alloy (HEA) CoCrFeMnNi over the full fatigue range comprised of low-cycle fatigue (LCF) and high-cycle fatigue (HCF). Through the analysis, it is shown that the TMW model is able to provide class A prediction for LCF (forecast before the event occurs) without resorting to fatigue testing; and with calibration at one stress level, it can be extended to the HCF regime. A relationship of fatigue life versus the total strain is established with the use of the Ramberg-Osgood equation. The TMW model predictions agree well with the experimental data and/or the Coffin-Manson-Basquin relation for the above materials. The TMW model describes the full-range fatigue life in terms of material’s elastic modulus, Poisson’s ratio, surface energy, and the Burgers vector. Thus it establishes a physics-based baseline for characterizing the effects of other contributing factors such as microstructure and surface roughness, which contribute to the uncertainty in the fatigue scatter.

2021-26-0255

9/22/2021

In a current competitive automotive market, weight and cost optimization is the need of an hour. Therefore it is important to explore use of alternative material which has less weight, low manufacturing cost and better strength. This paper presents methodology to achieve cost & weight reduction through use of Austempered Ductile Iron (ADI) instead of alloy forging. ADI casting has lower density, physical properties at par with alloy forgings and lower manufacturing cost. Pivot arm is the one of the critical component of twin axle steering system which transfers the hydraulic torque from steering gearbox to second forward axle via linkage system. In order to design lightweight pivot arm, existing chromium alloy steel material is replaced with the Austempered ductile iron (ADI). Pivot arm is designed and validated digitally as well as bench test and results are found to be meeting cost and weight targets. Weight reduction of 11.6 % achieved using ADI in place of chromium alloy steel and also part is meeting the structural and durability criteria.

Tool Wear Analysis on Drilling Process of Inconel 718 Superalloy

2020-01-0034

3/10/2020

The Inconel 718 is an alloy based on nickel of high thermal and mechanical resistance, which allows its wide application in the aerospace industry, being generally implemented in aircraft tail cone and engine components. On the other hand, these features become a recurring problem when the machining of this material is performed. For example, in the drilling process of this superalloy, the cutting tools used exhibit excessive wear due to the high temperature and pressure at the cutting edge. However, there are numerous parameters that can influence the cutting tool life, and when analyzed and well defined, determine the types of modifications needed to enable less wear, and consequently an increase of its useful life in service. Given this context and knowing that the study of tool life in the Inconel 718 drilling process is extremely relevant in the aerospace sector, this paper presents a wear study in order to evaluate the behavior of different types of cutting tools used to drill the Inconel 718. It was accomplished by the combination of different cutting parameters to perform the mechanical drilling tests on Inconel 718 sheets, using the Taguchi method as a quality tool for process investigation, and consequently the wear analysis of the cutting tools.

A stainless future

AUTOJUN09_06

6/1/2009

A push is under way to move stainless steel into more vehicle applications than just exhaust systems-notably structural parts and fuel cells. No, the automotive industry is not going Back to the Future. So don't expect any vehicles with exposed stainless steel (SS) body panels and gull-wing doors-á la the DeLorean DMC-12 of the early ‘80s-in mass production any time soon. Even so, industry experts such as Tom Long, Manager of Specialty Steel Sales for Ohio-based AK Steel, do expect the percentage of the corrosion-resistant material within each vehicle to increase in coming years. Unlike in the past decade, when much of the growth resulted from its traditional role in the exhaust system, as dual exhausts became more popular and vehicle sizes swelled, future growth is likely to come from its use in non-exhaust applications as well.
