Effects of wire-EDM parameters on the surface integrity and mechanical characteristics of additively manufactured Inconel 939

A systematic review of Inconel 939 alloy parts development via additive manufacturing process

“…However, they lacked strain to failure, achieving only a maximum of 6.4 %, half of the failure strain in the as-cast condition. The current issue with fatigue testing is that only low cycle fatigue evaluation has been carried out by Kanagarajah at a temperature of 750 °C, with a strain amplitude of 0.5 %, a strain rate of 6 × 10 −3, and an R ratio of −1 [ 64 , 83 ].…”

“…In light of the works produced, an extensive gap remains in the parametric investigation IN939 formed by LPBF, particularly the formation of single tracks and the recurring parameters influenced by high-power laser, carried out by Ozaner [ 64 ]. Multiple samples of 15 × 15 × 15 mm 3 with the first batch in random scanning followed by the second batch with accurate strategy and variation in laser power and scanning speeds.…”

Effect of Wire Electrical Discharge Machining on the Surface of Ebm-Additive Manufactured Niti Alloys

“…Studies shows that during micro-EDM machining, constituent elements of the tool material are deposited on the sub-surface and coat an antibacterial layer by controlling the process parameters including dielectric fluid, and pulse energy. On the other hand, the wire electrical discharge machining offers various post processing options, such as processing the holes, sample preparation for tensile and compression tests to obtain the final geometry of the workpiece [13,14]. The surface finish and dimensional accuracy of specimen are significantly vital for the engineering applications.…”
