Product description

Option 29

• How does the cooling rate affect the structure of the crystallizing metal? Explain

Essence of impact.

• What heat treatment is used after cold plastic deformation

To remove hardening? Justify the choice of mode (for example, aluminum) and describe

Occurring transformations.

• 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 a phase rule) for an alloy containing 1.5% C. What is the structure of this

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

• Using the iron-iron carbide state diagram, determine the temperature

Normalization, annealing, quenching of steel 45. Describe these modes of heat treatment and

Describe the structure and properties after each treatment.

• What are the advantages and disadvantages of surface hardening of steel products at

Heating by currents of high frequency in comparison with hardening by cementation method? Name it

Steel grades used for these types of processing.
