Metallurgy Matters: Phases, structures, and the influences

Phase diagrams, also known as constitution diagrams or equilibrium diagrams, graphically represent the influences of alloy composition and temperature on phase changes and solidification. Figure 1 In other words, for a given alloy, the phase diagram can show the phases and percentage of each phase present at a specific temperature and alloy

Steel Wikipedia

Sep 11, 2001 Steel is an alloy of iron with typically a few percent of carbon to improve its strength and fracture resistance compared to iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant need typically an additional 11% chromium.Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains

Big River Steel Doubles Capacity with Expansion Big

Nov 18, 2020 Big River Steel announced today that it successfully started up the second phase of its Arkansas-based scrap metal recycling and flat-rolled steel production facility. The Phase Two expansion budgeted at $716 million will double Big River Steel’s production capacity to 3.3 million tons annually. “When describing the success of our Phase Two

Mar 11, 2013 Thus, it is the temperature corresponding to gamma + alpha / gamma phase boundary for hypo-eutectoid steel and is a function of carbon content of the steel, as it decreases from 910 deg C at 0 % C to 727 deg C at 0.76 % C. It is also called the upper critical temperature of hypo-eutectoid steels. The temperature interval between A1 and A3
