Effects of magnetic field and post-weld heat treatment on microstructure and properties of laser welded joints of 22MnB5-TRIP590 steel

open access: yesMaterials Research Express
Laser welding without and with an auxiliary magnetic field (B = 30 mT) is performed on 22MnB5-TRIP590 steel. Subsequently, post-weld heat treatment, involving quenching at 800 °C followed by tempering at 200 °C, is carried out on the welded joints ...

Toward Knowledge‐Guided AI for Inverse Design in Manufacturing: A Perspective on Domain, Physics, and Human–AI Synergy

open access: yesAdvanced Intelligent Discovery, EarlyView.
This perspective highlights how knowledge‐guided artificial intelligence can address key challenges in manufacturing inverse design, including high‐dimensional search spaces, limited data, and process constraints. It focused on three complementary pillars—expert‐guided problem definition, physics‐informed machine learning, and large language model ...

Civilian Occupational Exposure to Vapors, Gas, Dust, or Fumes and Respiratory Health Among United States Military Veterans

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background We investigated associations of self‐reported and job exposure matrix (JEM) assigned civilian occupational exposure to vapors, gas, dust, or fumes (VGDF) with respiratory symptoms among previously deployed US Veterans. Methods An interviewer‐administered questionnaire ascertained self‐reported civilian occupational VGDF exposure.

Sensitivity analysis and stochastic optimization of levelized cost of hydrogen production through methane pyrolysis

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Hydrogen plays a crucial role across multiple industrial sectors and is increasingly recognized as a clean energy carrier with significant potential in decarbonization efforts. Methane pyrolysis (MP), particularly using molten metal catalysts, offers a promising pathway for hydrogen production with low CO2 emissions.

Analysis of corrosion damage in a boiler made of AISI 304L stainless steel

open access: yesZaštita Materijala, 2014
The corrosion damage near the welded joint in the boiler of AISI 304L stainless steel was analysed. During welding, heat tint was formed near the weld on the inner surface of the boiler, because shielded gas was not applied.
