“…Few have used nickel superalloys and austenitic steel such as SS316 and IN718 [10,11], but only a few literature are found on IN625 and SS304L [12]. Besides FGM, very few works are reported in IN625 and SS304L [13][14][15]. Carroll et al [12] deposited a single block of IN625-SS304L FGM in which they characterised and did the chemical analysis using CALPHAD of the gradient.…”

Functionally graded material (FGM) is an advanced material that illustrates the number of properties in a single component. To develop FGM, it is very important to study each component gradient separately to understand the properties and their behaviour. This paper presents the study of the properties of deposited blocks of the different gradients of Inconel 625 (IN625) and stainless steel 304L (SS304L) (25% IN625 + 75% SS304L, 50% IN625 + 50% SS304L, 75% IN625 + 25% SS304L, and 100% IN625) by a laser directed energy deposition technique. Various tests were performed to understand its mechanical, metallurgical, and chemical behaviour. Deposited samples were heat-treated and then optical microscopy and microhardness were measured and compared to untreated ones and results found to be comparatively improved.

“…But a separate analysis of the gradient of the FGM was missing. Further, [13] is a study on the influence of wire electro discharge machining parameter on LDEDed IN625 block and mix of IN625 and SS304L. Whereas, [14] is microstructure and hardness analysis of dissimilar joining of IN625 and SS304L by the electron beam welding process.…”

“…Very few works are reported in the fabrication of functionally graded SS304L/IN625. [20][21][22][23] Carroll et al 20 developed an FGM block of a square crosssection of 16 mm wide and 34 mm tall by 910 W YAG laser using the DED technique. They conducted experimental and thermodynamic studies on FGM and found the presence of (Mo,Nb)C secondary phase which is responsible for crack development.…”

In this paper, the effect of process parameter on functionally graded materials (FGMs) of Inconel 625 (IN625) and Austenitic steel (SS304L) deposited by laser directed energy deposition (LDED) are investigated. For this purpose, FGM walls of different gradient of mix of IN625 and SS304L at different layers are deposited on Austenitic steel (SS316L) substrate at different sets of process parameters. For this study, the process parameters considered are laser power ( PL): 1000, 1300 and 1600 W, and scanning speed ( v): 0.3, 0.5 and 0.7 m/min. Deposited samples are then subjected to different tests such as energy dispersive spectroscopy (EDS), microhardness, scanning electron microscopy (SEM), X-ray diffraction (XRD), optical microscopy (OM), and nanoindentation. Tests performed on the samples revealed different effects of parameters on the deposition of the FGM wall. Based on the comparison of results of mechanical and metallurgical tests, it is observed that either at PL = 1300 W and/or v = 0.5 m/min, among the considered process parameters, show comparatively better results than the others.
