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

open access: yessteel research international, Volume 97, Issue 6, Page 3267-3281, June 2026.
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.

Declining Runoff Sensitivity to Precipitation Following Permafrost Degradation: Insights From Event‐Scale Runoff Response in the Yellow River Source Region

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Frozen ground, including permafrost and seasonally frozen ground (SFG), is a critical element of the cryosphere that strongly regulates hydrological processes in cold regions. It has been debated whether frozen ground degradation will make landscapes more, or less, sensitive to precipitation inputs; either outcome has profound implications for

On the Role of Electron Precipitation in Excess Radiation Doses Measured at Aviation Altitudes

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract Radiation from space in the form of galactic cosmic rays (GCRs) generates a persistent background of ionizing radiation in Earth's atmosphere. The dose rate of ionizing radiation due to GCRs increases from sea level to aviation altitudes.
