“…8,9 Three build strategies of direct deposition, compositional gradation and use of an intermediate bond layer were attempted by Onuike et al 10 to build Inconel 718 and Ti6Al4V bimetallic structures by laser engineered net shaping, but only the approach using an intermediate bond layer produced a crack-free structure. Shang et al 11 adopted Cu as the intermediate bond layer for laser deposition manufacturing of a TA15 and Inconel 718 bimetallic structure, and the results showed that the Cu interlayer can achieve a plastic transit between the two metals and eliminate cracks at the interfaces. Wei et al 12 fabricated a functionally graded material that grades from Inconel 625 to Ti6Al4V by directed energy deposition and laser synchronous preheating, and they found that laser synchronous preheating is an effective measure on crack suppression.…”

“…However, nondestructive testing and evaluation for bimetallic structures are rarely studied, and it is an important link for the application of bimetallic structures in engineering. 13 Bimetallic structures formed by titanium alloy and Ni-based superalloy can obtain both a lightweight performance and an elevated temperature performance, 11,14 which are promising for aerospace industry. 10,12 In the present study, TA15 and Inconel 625 (IN625) powders were adopted to fabricate bimetallic samples by LMD.…”

Additive manufacturing of bimetallic structures has become a hotspot in recent years. However, the interfaces of bimetallic structures are always the weaknesses, and cracks always occur at the interfaces. Three bimetallic samples of TA15 and Inconel 625 were manufactured by laser metal deposition, and the effect of laser power on the manufacturing quality was analyzed. Then phased array ultrasonic testing (PAUT) technique was applied for crack detection for the three samples, and metallographic analysis was employed to verify detection results. The results showed that the increase of laser power can eliminate macro-cracks at the interface of the bimetallic sample, and micro-cracks at the interface can be detected by PAUT.

“…With considering the results of materials characteristics, the range of energy density for the LENS process is suggested between 98.21 to 107.14 J/mm 2 . Shang et al [5] successfully produced of bimetallic structure from TA15 to Inconel 718 via Copper interlayer via Laser deposition manufacturing. The construction of two metal structures has a special advantage in reducing the weight of the metal structure and using the excellent properties of both metal.…”

In this study direct laser metal deposition (DLMD) technique is adopted for the additive manufacturing (AM) of Inconel 718 Superalloy. To conduct the experiments, a 1 kW fiber laser with a coaxial nozzle head is used. The effects of scanning speed (for two values of 2.5 and 5 mm/s) as well as powder feed rate (for two values of 17.94 and 28.52 g/min) on the process were investigated. Characteristics of the 3D printed wall specimens such as the geometrical dimensions (width and height), microstructure observations, and the microhardness were obtained. In order to study the stability of the 3D manufactured walls, the height stability was considered for the investigation. Optical microscopy (OM), field emission electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), and mapping analysis were performed to derive the microstructural features of the additive manufactured samples. The Vickers microhardness test is used to evaluate the hardness distributions of additively manufactured parts. Catchment concept of the powder in DLMD process is used for explaining different trends of the process. Results indicated that, by decreasing the scanning speed, the width and height of the deposited layer increase. The average width of the additively manufactured samples directly depends on the scanning speed and the powder feed rate. Scanning speed has a reverse effect on the height stability; that is, the lower the scanning speed, the larger the stability. Microstructural results showed that because of the solidification process, the alloying elements will be accumulated in the grain boundaries. The non-uniform cooling rate and non-steady solidification rates of molten area in additive manufacturing process, the microhardness values of the additively manufactured samples following a fluctuated trend.
