Foundry Materials: Cast Irons

This lecture covers the iron-carbon phase diagram with different phases such as liquid, austenite, ferrite, and cementite. It discusses the flowability and castability of metals, as well as the characteristics of hypo-eutectic cast iron and hyper-eutectoid steel. The lecture also delves into the crystallization of cast irons, including white cast irons and gray cast irons, based on their carbon and silicon content. It explains the advantages and disadvantages of white and gray cast irons, their applications, and properties. Additionally, the lecture touches on copper alloys, aluminum, and zinc alloys commonly used in foundry processes.
