Option 21
1. What are the characteristic properties of metals and how are they determined?
2. How is the temperature of the metal and alloy recrystallization threshold set?
Give some specific examples.
3. Draw a diagram of the iron-iron carbide state, indicate the structural
Components in all areas of the diagram, describe the transformations and construct a curve
Cooling (using the phase rule) for an alloy containing 0.3% C. What is the structure of this
Alloy at room temperature and how such an alloy is called?
4. After quenching of carbon steel, a martensite + cementite structure was obtained.
Put on the state diagram iron-cementite ordinate (roughly) of the processed steel,
Indicate the temperature of its heating for quenching. Describe the transformations that have occurred
With heating and cooling of steel.
5. Products made of steel 45 are required to be improved. Assign a thermal mode
Processing, describe the nature of the transformations that occur, the structure and properties of steel after
Processing.
