Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

open access: yessteel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

open access: yessteel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Formal Approach to Safety‐Driven Dynamic Procedure Modeling

open access: yesSystems Engineering, EarlyView.
ABSTRACT Ensuring the safety of unmanned aerial systems (UAS) is a growing concern as the number of UAS grows increasingly fast. Regulatory bodies are in the process of tackling this problem by issuing standards and recommendations to be met by UAS designers.

Prognostic Impact of Internal Jugular Vein Invasion Through Extrathyroidal and Extranodal Extension in Papillary Thyroid Carcinoma

open access: yesWorld Journal of Surgery, EarlyView.
ABSTRACT Background IJV invasion is a rare but significant occurrence in PTC. Although the current staging system categorizes T stages based on organ invasion, the classification for IJV invasion remains unclear. We evaluated the prognostic impact of internal jugular vein (IJV) involvement by extrathyroidal extension (ETE) and extranodal extension (ENE)
