High Strength Microalloyed Steels for Petroleum Pipelines : At present, due to worldwide increased demand for oil, there is a need to develop exceptionally strong (yield strength of @800 MPa) steels for pipelines. Such strong steels allow for operating the pipelines under higher pressures and over a long distance. Such microalloyed steels often can contain such elements as Mn, Nb, V, Ti, Mo, Ni, Cr, and Cu.    (a) What other factors must be considered for high-strength steels for oil pipelines?  (b) Based on what you have learned in terms of mechanisms of strengthening, how can you choose the best possible alloying elements for this application? Assume that you can conduct whatever experiments are necessary.
