Texture Dependent Mechanical Anisotropy of X80 Pipeline Steel
Advanced Engineering Materials, 2010 AbstractPipeline steel grades API X80 are used for oil and gas transport. The most important mechanical properties of these steel grades are strength and fracture toughness. A remarkable directional anisotropy of toughness and strength were often observed in the plates.
