Effect of Microstructural and Crystallographic Texture Parameters on the Fracture Energy Absorption of X90 Pipeline Steel

Металлы / Russian Metallurgy
The microstructure, substructure, and crystallographic texture of X90 pipeline steel were studied using optical and electron microscopy, electron backscatter diffraction (EBSD), and X-ray texture analysis. Fracture energy absorption was measured by drop-weight tear testing.

Experimental Study on the Fracture Toughness of Welded Joints of API X90 High-grade Pipeline Steels Using Single-Edge-Notched Tension Specimens

Arabian Journal for Science and Engineering, 2018
The fracture toughness and R-curves of welded joints of API X90 pipeline steels were experimentally studied. Single-edge- notched tension (SENT) specimens and a normalization method were adopted. Joints welded by using three technologies (A, B, and C) were investigated.
