Cladding is a proven method that boosts the surface qualities of mechanical parts by applying a layer of more durable material over a base substrate. This work responds to the needs of offshore and pressure vessels sectors by focusing on cladding a super austenitic steel onto low‐carbon steel through gas tungsten arc welding.

Raman amplification and pulsed lasing in cladding-pumped germanosilicate fiber
We report for the first time Raman amplification in a cladding-pumped fiber. The double-clad germanosilicate fiber was pumped by a Q-switched Er-Yb co-doped fiber laser at 1570 nm. The power conversion efficiency was up to 36%, with a slope of 64%

Laser cladding using scanning optics
Laser cladding using scanning optics is a relatively little studied matter. Scanning optics makes the adjustment of laser beam interaction zone numerically possible and it is, therefore, a more flexible optical tool than the conventional static optics. A

High‐Power Single‐Quantum‐Well 376 nm Ultraviolet A Laser with Low‐Threshold Current Density
A 376 nm ultra‐violet A (UV‐A) laser diode is demonstrated using a GaN waveguide and single‐quantum‐well active region to reduce optical loss and structural strain while improving carrier distribution. The device achieves 2.36 W output power, 822.9 mW/A slope efficiency, and 5.89 kA/cm2 threshold current density, showing a promising route toward high ...

Atom Probe Tomography‐Based Analysis of Residual Trace Elements in Advanced Metallic Materials
ABSTRACT Residual trace elements inherited from raw materials strongly influence the mechanical and environmental performance of advanced metallic alloys and recycling materials due to preferable boundary/interface segregation and resultant embrittlement effects, yet their parts per million level concentrations pose significant challenges to ...

The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...
