Recent years have witnessed increasing demand for selective laser melting (SLM) in practical applications; however, determining the appropriate process parameter range remains challenging. In this study, a framework was developed to determine considering occurrence of defects and cracks by conducting single-track test thermal elastoplastic analysis. Keyholing, balling, residual unmelted regions...

A new accelerated creep assessment method to evaluate the performance of metals and alloys from high-temperature tensile tests, i.e. slow-strain-rate testing (SSRT), is proposed evaluated. The consists decomposing inelastic strain into a plastic component by adopting general assumptions on behaviour materials, formulated using state variable formalism verified tests with intermediate dwell time...

Quality control of mechanical components is crucial to ensure their expected performance and prevent failure. For manufactured additively, quality performed in-process particularly interesting, as the sequential deposition remelting layers represent a possibility mitigate existing flaws. The first step towards closed-loop that monitoring setup data analytics approach can flag discriminate This ...

A multi-aperture shower design is reported to improve the transverse uniformity of GdYBCO superconducting films on the template of sputtered-LaMnO₃/epitaxial-MgO/IBAD-MgO/solution deposition planarization (SDP)-Y₂O₃-buffered Hastelloy tapes. The GdYBCO films were prepared by the metal organic chemical vapor deposition (MOCVD) process. The transverse uniformities of structure, morphology, thickn...

Activated tungsten inert gas welding (ATIG) is a new approach to Tungsten Inert Gas (TIG) that has the potential improve weld penetration. This paper investigates effect of micro and nanoparticle size oxide flux during TIG Hastelloy C-22. The SiO<sub>2</sub> Al<sub>2</sub>O<sub>3</sub> fluxes in terms particle thermal stability on surface appearance, bead geo...
