Ultra Short Pulse Laser Welding of Glass to Metal in the Low Fluence Regime
Laser &Photonics Reviews, EarlyView.Ultrashortpulse laser welding enables precise joining of glass and metal with minimal thermal damage. We introduce the TwoThresholds Criteria to identify suitable laser parameters by combining the nonlinearabsorption threshold in glass with the metalmodification fluence threshold.

Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit
Materials and Corrosion, EarlyView.The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with

Materials and Corrosion, EarlyView.This article examines the impact of externally introduced chromium compounds on the localized corrosion of 316 L stainless steel in acidic chloride environments such as hydrochloric acid. While the corrosion resistance of 316 L relies on the formation of a chromium‐rich passive oxide layer, industrial conditions may expose the steel to various chromium
