Mechanical behaviour of two low alloy steels (G11 and G12) was studied with respect to different phosphorus contents. Tensile strength and yield strength increased while percentage elongation at fracture decreased on increasing phosphorus content. The SEM and light optical photomicrograph of low phosphorus steel (G11) revealed ferrite and pearlite microstructure. On increasing phosphorus content from 0.25 wt.% to 0.42 wt.%, the morphology of grain changed from equiaxed shape to pan-cake shape and grain size also increased.

The modified silicate is analysed by X-ray which suggested intercalation of elastomer chains into silicate layers. Rheological measurement as well as mechanical properties showed both nanoclay and calcium carbonate give rise to a marked increase in elastic modulus and viscosity which could be attributed to the good interaction between po

Abstract Biocorrosion is routinely encountered, but not always recognized, in the oilfield. Biocorrosion results primarily from the activities of sessile (adherent) bacteria growing in biofilms on metal surfaces. Classical microbiological methods are not appropriate for detecting or monitoring sessile bacteria. In the work reported here, biofilming bacteria, their associated exopolymer, and the early time-course events of biofilm development on steel were visualized by use of the scanning electron microscope (SEM).

Recently, a corrosion mechanism for the action of SRB on iron was proposed, which seeks to explain the initiation of this kind of corrosion in order to improve prevention and mitigation techniques. This mechanism was supported on the fact that there should be a local pH decrease at the metal/solution interface. So, the principal aim of this work was to prove t
