The development of additive manufacturing, or three-dimensional (3D) printing, technologies has produced breakthroughs in the design and manufacturing products by enhancing freedom minimising steps. In addition, complex, unique microstructures imparted processes offer prospects unprecedented advances to produce high-performance metal alloys for high-temperature corrosive environments. Here, we ...

The prediction of the equilibrium and metastable morphologies during solidification Ni-based superalloys on mesoscopic scale can be performed using phase-field modeling. In present paper, we apply model to simulate evolution microstructures depending undercooling in a quasi-binary approximation. results modeling are compared with experimental data obtained samples alloy Inconel 718 (IN718) proc...

This research work studies the structural phase parameters and physicomechanical properties of metal-matrix composite materials based on a Ni–TiB2 system obtained by additive manufacturing (specifically, direct laser deposition). The composites were investigated at high temperatures (up to 1000 °C). feasibility fabrication nanostructure alloy with advanced was shown. introduction reinforcing Ti...

In this study, residual stresses from the electron beam additive manufacturing (EBAM) and selective laser melting (SLM) processes, due to repeated thermal cycles, were investigated. Residual stresses play a crucial role in part performance, and thus, it is critical to evaluate the process-induced residual stresses in AM parts. Ti-6Al-4V and Inconel 718 parts produced by EBAM and SLM, respective...

The electrochemical behavior of nickel, Inconel 600, Incoloy 800 and 316 stainless steel electrodes in different concentration of NaOH solution was investigated using the cyclic voltammetry technique (CV). All the curves in the anodic branch of the CV are characterized by anodic dissolution peak (A), passive region (B), anodic dissolution peak (C) before oxygen evolution. In the case of the cat...

The characterization of Ni-based superalloy Inconel® 718 fabricated by powder-based laser fusion process was performed to study microstructural evolution and accompanying mechanical properties as-deposited post-heat-treated material. current effort employs a low volumetric energy density during the deposition. X-ray diffraction, optical, scanning electron microscopy were done for characterizati...

Laser direct metal deposition (LDMD) has developed from a prototyping to a single metal manufacturing tool. Its potential for creating multimaterial and functionally graded structures is now beginning to be explored. This work is a first part of a study in which a single layer of Inconel 718 is deposited on Ti-6Al-4V substrate. Single layer tracks were built at a range of powder mass flow rates...
