1Chapter P. Phase diagrams. After studying this chapter, you will be able to P1. Sketch the phase diagram of a solid solution and analyze this diagram: determine the composition and amount of each phase for a given overall composition and temperature. P2. Sketch the phase diagram of a simple eutectic alloy and define the eutectic point, liquidus, solidus and solvus lines. Analyze this diagram in terms of number, composition and amount of the phases. P3. Sketch a simple phase diagram with an intermediate compound and analyze the diagram in terms of number, composition and amount of phases. P4. Analyze the phase diagram of the iron-carbon system that underlies steel.
