The effect of flow on corrosion behaviour carbon steel under intermittent oil/water wetting was investigated by a newly-modified “alternate cell”, combining with the use potentiostatic polarisation, in-situ visualisation, contact angle measurements and scanning electron microscopy (SEM). time determined formation thin film electrode surface after transition immersion state. A short alternate pe...

In the present study, effect of inclusions characteristics changing on the formation of acicular ferrite in submerged arc welding of API5l-X65 low alloy steel was investigated. Three different welding fluxes with different chemical composition and basicity index of 0.72, 0.82 and 0.99, and two different welding heat inputs of 1.6 kJ / mm and 2.4 kJ / mm were used to create inclusions with diffe...

Till now, different constitutive models have been applied to model the hot deformation flow curves of different materials. In this research, the hot deformation flow stress of API X65 pipeline steel was modeled using the power law equation with strain dependent constants. The results was compared with the results of the other previously examined constitutive equations including the Arrhenius eq...
