Product description
Option 46
1. What explains the high electrical and thermal conductivity of metals?
2. How does the structure and properties of the metal change under cold plastic deformation?
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 1.2% C. What is the structure of this
Alloy at room temperature and how such an alloy is called?
4. 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 55 HRC.
Indicate how this regime is called, describe the nature of the transformations and what structure
Is obtained in this case.
5. Forgings of steel 40 have a coarse-grained structure. Using the status diagram
Iron-cementite designate a heat treatment mode for obtaining fine grains and
Explain why the selected mode provides fine-grained steel structure.
