The use of ammonia as a hydrogen carrier requires efficient cracking technology. A promising solution is the membrane reactor (MR), which enables both decomposition and separation to take place within same device, providing advantages in terms efficiency compactness compared conventional systems. literature reports that ceramic-supported double-skinned Pd-Ag membranes show outstanding performan...

This study analyses literature data to identify optimised print parameters and assesses the consolidation, microstructure, mechanical properties of Hastelloy-X printed by laser powder bed fusion. Effects post annealing hot-isostatic pressing (HIP) on microstructure are also revealed. The susceptibility solidification cracking was evaluated basis gradient freezing range obtained via calculation ...

To optimize and satisfy current industrial requirements, during the last decade new alternatives to conventional manufacturing processes are implemented into machines, leading multitasking machines. Especially hybrid machines combining additive subtractive technologies (AM/SM), have become a potential solution for repairing operations in terms of material waste reduction, time consumption flexi...

Abstract Hastelloy C276 is widely used in the new generation of nuclear power plants, and hot deformation optimum way to form part. In this investigation, constitutive modeling alloy are researched, processing maps drawn. The results show that strain rate temperature have remarkable impacts on behaviors alloy. yield behavior flow stress predicted based Arrhenius equation, correlation coefficien...

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...
