The tie-line rule is a graphical method used in the field of thermodynamics to determine the compositions of two phases that are in equilibrium with each other. This rule is often used in the context of phase diagrams, which are diagrams that show … [Continue reading]
Explain Invariant Reactions
Invariant reactions are chemical reactions that occur at constant temperature and pressure and produce a fixed set of products, regardless of the initial conditions or reactants. In other words, the reaction proceeds in a way that is independent of … [Continue reading]
Microstructural Changes during Cooling
During cooling, microstructural changes during cooling occur in materials due to changes in their atomic and molecular arrangements. These changes can affect the material's properties, such as its strength, toughness, and ductility. When a … [Continue reading]
Martensite | Properties of Martensite
Martensite is a term used to describe a specific microstructure that forms in some types of steel and other metals during rapid cooling. The microstructure is characterized by an acicular, needle-like appearance and a high degree of hardness and … [Continue reading]
Microstructural Changes in Martensite
During tempering, the microstructural changes in martensite undergoes several changes. Martensite is a high-strength and brittle phase that forms when austenite, a face-centered cubic crystal structure, is rapidly quenched to room temperature. … [Continue reading]
