Laser Directed Energy Deposition-Based Additive Manufacturing of Fe20Cr5.5AlY from Single Tracks to Bulk Structures: Statistical Analysis, Process Optimization, and Characterization

open access: yesMachines, 2023
Laser directed energy deposition (LDED) can be deployed for depositing high-performance materials for various engineering applications. Alumina-forming steel is a high-performance material that possesses excellent corrosion and oxidation resistance ...

Asymptotic analysis of silicon based Bragg fibers [PDF]

open access: yes, 2003
We developed an asymptotic formalism that fully characterizes the propagation and loss properties of a Bragg fiber with finite cladding layers. The formalism is subsequently applied to miniature air-core Bragg fibers with Silicon-based cladding mirrors ...

Bowing and expansion of natural stone panels: marble and limestone testing and assessment

open access: yesMateriales de Construccion, 2008
Natural stone has been used as a building material for centuries. In the past, load bearing members were made of entirely of stone, but in the last 50 years new processing techniques have made the production and use of thin facade cladding a profitable ...

Monumental arrangements of the Łysa Góra ceramic panels in the decoration of church buildings

open access: yesSacrum et Decorum, 2021
Ceramic panels produced since 1960 in the “Kamionka” cooperative in Łysa Góra are one of the most versatile materials used for architectural decorations. They made it possible to create small “ceramic accents” as well as large-scale and monumental works.

Hot Forging of a Cladded Component by Automated GMAW Process [PDF]

open access: yes, 2010
Weld cladding is employed to improve the service life of engineering components by increasing corrosion and wear resistance and reducing the cost. The acceptable multi-bead cladding layer depends on single bead geometry.

Metallurgical Characterization of the Interfaces in Steel Plates Clad with Austenitic Steel or High Ni Alloys by Hot Rolling

open access: yesMetals, 2020
An integrated experimental-theoretical approach to the metallurgical characterization of the interfaces in steel plates clad by hot rolling is proposed. Three different couplings of materials have been studied: ASTM A 515 Gr.60 low carbon steel clad with

Co-axial dual-core resonant leaky fibre for optical amplifiers [PDF]

open access: yes, 2008
We present a co-axial dual-core resonant leaky optical fibre design, in which the outer core is made highly leaky. A suitable choice of parameters can enable us to resonantly couple power from the inner core to the outer core. In a large-core fibre, such

Ultra-broadband wavelength-swept Tm-doped fiber laser using wavelength-combined gain stages [PDF]

open access: yes, 2015
A wavelength-swept thulium-doped fiber laser system employing two parallel cavities with two different fiber gain stages is reported. The fiber gain stages were tailored to provide emission in complementary bands with external wavelength-dependent ...

FEM investigation of leaky modes in hollow core photonic crystal fibers [PDF]

open access: yes, 2007
Hollow-core holey fibers are promising candidates for low-loss guidance of light in various applications, e.g., for the use in laser guide star adaptive optics systems in optical astronomy.

Peculiarities of laser cladding with feeding of the filler tape

open access: yesЛитьë и металлургия, 2018
Semiconductor laser has some features that make it an efficient tool for surface treatment of metals, in particular for surface strengthening. It provides high enough concentration of energy in the heat spot, possibility to adjust process parameters in ...
