Heat transfer and fluid flow during electron beam welding of 21Cr–6Ni–9Mn steel and Ti–6Al–4V alloy
Electron beam welding (EBW) of two important engineering alloys, Ti–6Al–4V and 21Cr–6Ni–9Mn, was studied experimentally and theoretically. The temperatures at several monitoring locations in the
Scientific, technological and economic issues in metal printing and their solutions
TLDR
3D printing is now widely used in aerospace, healthcare, energy, automotive and other industries, and is the fastest growing sector, yet its development presents scientific, technological and economic challenges that must be understood and addressed.
Metallurgy, mechanistic models and machine learning in metal printing
Additive manufacturing enables the printing of metallic parts, such as customized implants for patients, durable single-crystal parts for use in harsh environments, and the printing of parts with
Development of a Near Net Shape Processing Method for Rhenium Using Directed Light Fabrication
Abstract Directed Light Fabrication (DLF) is a direct metal deposition process that fuses gas delivered powder, in the focal zone of a high powered laser beam to form fully fused near net shaped
Modelling and validation of multiple reflections for enhanced laser welding
The effects of multiple internal reflections within a laser weld joint as functions of joint geometry and processing conditions have been characterized. A computer-based ray tracing model is used to
Microstructural evaluation of low and high duty cycle Nd:YAG laser beam welds in 2024-T3 aluminium
The propensity for hot tearing and porosity in pulsed Nd-YAG laser beam welding of 2024-T3 aluminum was observed to vary with beam on'' duty cycle. High average laser output power of 1 kW and
Near net shape processing for solar thermal propulsion hardware using directed light fabrication
Directed light fabrication (DLF) is a direct metal deposition process that fuses gas delivered powder, in the focal zone of a high powered laser beam to form fully fused near net shaped components.
