Equilibrium diagrams show what phase changes occur at what temperature in differentalloys. Answer the following questions about equilibrium diagrams:i) Draw the shape of a combination type equilibrium diagram. (5 marks)ii) The Iron-carbon equilibrium diagram is an example of a combination typebut it contains a eutectoid point as well as a eutectic point. Describe whathappens at these two points. (6 marks)iii) Describe the structure and properties of eutectoid steel at roomtemperature. (6 marks)iv) Briefly explain why the equilibrium diagram is important when heat treatingsteel.
