Hierarchical Twin Networks Enable Exceptional Strength and Fracture Toughness in Titanium

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A commercial‐purity titanium with hierarchical ultrafine twin structures delivers an exceptional combination of fracture toughness (KJIc) of 187 MPa·m1/2 and specific yield strength of 140 MPa·cm3·g−1, in which pre‐engineered high‐density twin boundaries stimulate massive and dislocations to blunt crack tip.

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels

steel research international, Volume 97, Issue 8, Page 4316-4325, August 2026.
The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of
