Garbuzova KR1 Option 48

Product description

Option 48

• What is eutectic? Give an example of an alloy with a structure

eutectic.

• What explains the hardening of metal during plastic deformation?
• Draw a state diagram of iron - iron carbide, indicate structural

components in all areas of the diagram, describe the transformations and plot the curve

cooling (using the phase rule) for an alloy containing 1.7% C. What is the structure of this

alloy at room temperature and what is this alloy called?

• Draw a diagram of the isothermal transformation of austenite h for steel U8.

Apply an isothermal curve on it to ensure hardness S00 HB. Indicate

how this mode is called and what structure is obtained during this processing.

• Assign the heat treatment mode of carbon structural steel,

used to reduce internal stress, hardness and improve

machinability by cutting. Give a concrete example.
