Title: Investigation of correlation of carbide size and percentage with mechanical properties of high strength low alloy steels

Technical Report ·
OSTI ID:7171293

The final report on the DOE Contract 86X-22006C gives the results of statistical analyses and research conducted in the period March 1, 1985 to July 31, 1986. Data generated in the previous DOE Contract (DE-AC05-78ET13513) was combined with carbide analyses performed in this contract. The project was designed to establish the role of composition (Mo,Cr,Mn,Si,C,P) and tempering parameter ona range of steel properties using a statistical design with 32 samples. Models representing the carbides formed as a function of these variables led to constitution diagram for Cr-Mo steels. Further analyses included the role of composition, carbides and the tempering parameter on the yield and ultimate tensile strength, the ductile-brittle transition temperature, the room temperature Charpy impact energy and the threshold stress intensity in a moist H/sub 2/S environment. 28 refs., 24 figs., 25 tabs.
