Tempering microstructure and mechanical properties of pipeline steel X80

Transactions of Nonferrous Metals Society of China, 2009
The tempering microstructure and mechanical properties of X80 steel used for heating-bent pipe were analyzed. The results show that the microstructure of X80 steel tempered at 550 ℃ and 600 ℃ is bainitic ferrite (BF)+granular bainite (GB), and partial ferrite laths in BF merge and broaden.

Synchronizing the Osteochondral Regeneration Process through Spatial Patterning of Stable and Hypertrophic Cartilage Organoids

Advanced Materials, Volume 38, Issue 33, 12 June 2026.
Zonated osteochondral assembloid implants are engineered through scaffold‐free spatial assembly of induced pluripotent stem cell (iPSC)‐derived chondrocyte organoids and periosteum‐derived osteogenic organoids. Implanted into full‐thickness rat osteochondral defects, they promote hyaline‐like cartilage repair, support subchondral bone formation with ...

FPGA Realization of a Novel Hyperchaos Augmented Image Encryption Algorithm

IET Computers &Digital Techniques, Volume 2026, Issue 1, 2026.
With the rapid growth of multimedia communication, protecting image data has become increasingly critical. This article proposes a novel 3‐stage hyperchaos‐based augmented image encryption technique (3SHAIET) that utilizes a three‐stage process with chaotic systems of increasing dimensionality (e.g., six‐dimensional [6D], 8D, and 9D) to enhance ...

Microbiologically influenced corrosion in aluminium alloys and premier techniques for comprehensive identification and characterization across diverse metal types

Journal of Chemical Technology &Biotechnology, Volume 100, Issue 6, Page 1143-1158, June 2025.
Abstract Microbiologically influenced corrosion (MIC) is acknowledged as a significant type of corrosion due to its extensive impact on metal/alloy surfaces. As MIC accounts for 20% of all corrosion instances, it is a critical factor causing service failure of engineering materials such as steel and aluminium alloy.
