To reduce costs and improve high-temperature performance in Advanced Ultra Super Critical (AUSC) boilers, it is necessary to weld austenitic steel Inconel alloy. In this study, the autogenous tungsten inert gas (TIG) welding process was used join Alloy 617 an AISI 304H plate of thickness 5 mm. Microstructural analysis showed that microstructure formation uneven along weldments, with columnar ce...

In the framework of H2020 European project POLYPHEM, whose main objective is to improve flexibility and performance small-scale solar power plants, studies have been conducted on various nickel-based alloys for design receiver. Inconel 600 alloy used as a reference material in advanced manufacturing high temperature receivers but other oxidation resistant selected such 617, Haynes 230, HR120 Ha...

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...

Titanium alloy Ti–6Al–4V and nickel-based superalloy Inconel 718 have been widely employed in modern manufacturing. The published literature on high speed machining (HSM) of the two materials often involves different machining set-up, which makes it difficult to directly apply the research findings from onematerial to the other to select the most appropriate tool geometry and cutting conditions...

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...
