The document discusses cooling curves and phase diagrams. It explains that a cooling curve graphs the solidification of molten metal over time and temperature, and can show pure metals, binary solutions, and binary eutectic systems. Phase diagrams show the phases present at different compositions and temperatures under equilibrium conditions. They include diagrams for complete and partial solid solubility, as well as those containing eutectic, peritectic, eutectoid, and peritectoid reactions. Interpreting phase diagrams allows determining phase composition and amount at any given conditions.
Iron – Carbon Diagram is also known as Iron – Carbon Phase Diagram or Iron – Carbon Equilibrium diagram or Iron – Iron Carbide diagram or Fe-Fe3C diagram
Cast iron is a group of iron-carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities.
History:
Cast iron was invented in China in the 5th century BC and poured into molds to make ploughshares and pots as well as weapons and pagodas. Although steel was more desirable, cast iron was cheaper and thus was more commonly used for implements in ancient China, while wrought iron or steel was used for weapons.
The cast-iron is manufactured by re-melting pig-iron with coke and limestone. This re-melting is done in a furnace known as the cupola furnace. It is more or less same as the blast furnace, but it is smaller in size. Its shape is cylindrical with diameter of about 1 m and height of about 5 m.
The working of cupola furnace is also similar to that of blast furnace. The raw materials are fed from top. The cupola furnace is worked intermittently and it is open at top. After the raw materials are placed, the furnace is fired and blast of air is forced through tuyeres. The blast of air is cold as the impurities in pig-iron are removed by the oxidation

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

10. Interpretation of phase diagrams
• Using a phase diagram, one can obtain at least
the following three transformations.
1. The phases that are present
2. The composition of each phase
3. The amount of each phase present.
11.
12. Types of Equilibrium Phase Diagram
• Plot the composition of phases as a function
of temperature in any alloy system under
equilibrium conditions.
1. Phase diagrams for complete solid solubility
2. Phase diagrams for partial solid solubility
3. Phase diagrams containing reactions
13. 1. Phase diagrams for complete solid

other in both in liquid and solid states is
known as isomorphous system.
