Electrochemical behaviour of X80 pipeline steel with alumina coating

Surface Engineering, 2015
X80 pipeline steel was firstly aluminised at a relative low temperature then treated by a microarc oxidation process. Electrochemical behaviour of X80 pipeline steel before and after the combined treatment was evaluated by electrochemical tests in different solution. Results show that ceramics coating composed of α-Al2O3 and γ-Al2O3 can be obtained on

Fracture toughness of the materials in welded joint of X80 pipeline steel

Engineering Fracture Mechanics, 2015
Abstract The microstructures, mechanical properties and fracture toughness of the materials in different locations of the welded joint of the X80 pipeline steel were studied at room temperature. Elastic–plastic fracture toughness testing of crack tip opening displacement (CTOD) and J-integral of the welding materials and base material were conducted.
