Garbuzova КР1 Option 03

Product description

Option 3

• Describe the types of solid solutions. Give examples.
• Give a definition of hardness. What methods measure the hardness of metals and alloys?

Describe them.

• Draw a state diagram of iron-iron carbide, 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 2.2% C. What is the structure of this

Alloy at room temperature and how such an alloy is called?

• Draw a diagram of the isothermal transformation of austenite for steel V8. Apply

On it is a curve of the isothermal treatment regime, which provides a hardness of 150 NW.

Specify how this mode is called and what structure is obtained in this case.

• Using the iron-cementite state diagram, justify the choice of the thermal

Treatment used to remove cementite mesh in the hypereutectoid steel.
