Garbuzova KR1 Option 31

Product description

Option 31

• Describe the point imperfections of the crystal structure of the metal. What are their

Effect on properties?

• Parts made of copper, stamped in the cold state, had a low plasticity.

Explain the reason for this phenomenon and indicate how you can restore plasticity.

Assign a processing mode and give the character of the change in structure and properties.

• 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 3.2% C. What is the structure of this

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

• Using the iron-cementite state diagram, determine the temperature of the total,

Incomplete annealing and normalization for steel 10. Describe these thermal regimes

And describe the structure and properties of steel.

• What is the treatment of cold steel and in what cases is it used?

(Explain using martensitic curves.)
