Garbuzova KR1 Option 13

Product description

Option 13

• What is subcooling and how does it affect the grain size of the crystallizing

Metal?

• What processes occur when the deformed metal is heated above the temperature

Recrystallization? In this case, the structure and properties change?

• 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 0.6% C. What is the structure of this

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

• What is normalization? Using the iron-cementite state diagram, indicate

The temperature of normalization of steel 45 and steel U12. Describe the transformations occurring in steels

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

• The cutting tool must be machined for maximum hardness. For his

Manufacture is selected steel U13A. Assign a heat treatment mode, describe the structure and

Properties of steel.
