  1. Phase Diagram. We shall interpret microstructrures in the context of the iron-carbon equilibrium phase diagram, even though steels inevitably contain other solutes, whether by design or as impurities.

  2. 10 mar 2020 · From 0.008% up to 2.14% carbon content, the iron-carbon alloy is called steel. Within this range, there are different grades of steel known as low-carbon steel (or mild steel), medium-carbon steel, and high-carbon steel. When the carbon content increases beyond 2.14%, we reach the stage of cast iron.

  3. 31 mar 2023 · For example, the preparation and design of new alloy composition, and the improvement of existing alloy properties (such as the phase to avoid brittleness in Fe-Cr alloy), all need to refer to the relevant phase diagram.

  4. Learn about the Fe-C phase diagram and understand the different phases and transformations that occur in iron-carbon alloys at various temperatures and compositions. Explore the phases such as austenite, ferrite, and cementite, and how they influence the properties of steel.

  5. alloy phase diagrams and the expansion and improvement of phase diagram databases. Single-Component Phase Diagram The number of constituents (components) is 1, and in most cases, the coordinates are pressure and temperature. The pure metal phase diagram belongs to the single-component phase diagram. Figure 1 is a schematic diagram of most pure

  6. 11 lut 2023 · Most practical metal materials are alloys composed of one or more alloy phases. The structure and properties of alloy phases and the relative content, grain size, shape, and distribution of each phase play a decisive role in the performance of the alloy.

  7. In their simplest form, steels are alloys of iron (Fe) and carbon (C), so we will be looking at phase transformations using the Fe-C phase diagram. This is a fairly complex phase diagram but we are only interested in the steels part of the diagram (up to around 7% carbon).
