Garbuzova KR1 Option 33

Product description

Option 33

• How do modifiers affect the crystallization process? Give examples

Practical use of the modification process.

• How is the temperature of the recrystallization threshold determined? How does the composition of the alloy and

The degree of plastic deformation at this temperature?

• 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 2.8% C. What is the structure of this

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

• What is hardening? Using the iron-cementite status diagram, indicate

Temperature of heating for quenching of steel 40 and U10. Describe the transformations occurring in steels

With the selected processing mode, the resulting structure and properties.

• Why is the steel used with the original structure used to make the tool

Granular perlite? As a result of what heat treatment can this structure be obtained?

Give a concrete example.
