Metallurgical and Mechanical Features of API 5L X65 Pipeline Steel Weldment
4th International Pipeline Conference, Parts A and B, 2002Substantial differences amongst metallurgical and mechanical properties of base metal (BM), weld metal (WM) and heat-affected zone (HAZ) occur in general in welded steel structures It is common practice in various engineering structures to evaluate the fracture performance of welded structures by mechanical testing.

Firefly algorithm assisted optimised NN to predict the elongation of API X65 pipeline steel
International Journal of Mathematical Modelling and Numerical Optimisation, 2013Selection of a proper neural network structure is a complicated work that is often done through the trial-and-error method. In this research, a three layer neural network with feed forward topology and back propagation algorithm is considered as a basic neural network model.

Erosion-corrosion of pipeline steel X65 and 22Cr duplex stainless steel in CO2 saturated environment
SPE International Oilfield Corrosion Conference, 2008Abstract An erosion-corrosion study on pipeline material degradation in sand-containing and CO2 saturated environments has been carried out. The total material loss, corrosion, erosion and their interactions (often referred to as synergy) have been assessed for pipeline steel X65 and 22Cr duplex stainless steel in various environmental ...

Effect of Zr–Ti deoxidisation on the hydrogen-induced cracking of X65 pipeline steels
Materials Science and Technology, 2016The effect of Zr–Ti combined deoxidisation, compared with the traditional Al deoxidisation, on inclusion and microstructure in X65 pipeline steels was investigated by means of analytical characterisation techniques such as non-aqueous solution electrolysis method, optical and electron microscopy in conjunction with energy dispersive X-ray spectroscopy ...

Austenization is an important stage during the quenching-tempering heat-treatment process of X65 microalloyed pipeline steel, because it can influence the development of final microstructure and mechanical properties. In this paper, a detailed investigation was carried out on the austenizing transformation process in X65 microalloyed pipeline steel ...

Modeling the hot deformation flow curves of API X65 pipeline steel
The International Journal of Advanced Manufacturing Technology, 2014In this paper, a new simple model was developed based on a power function of Zener–Hollomon parameter and a third-order polynomial function of strainm (m is a constant) to model the hot flow stress of API X65 pipeline steel. The results of the developed equation for modeling the hot flow stress of API X65 pipeline steel was compared with two other ...
