Material Science - test work number 1
Option 9
1. Describe the features of the metallic type of bond and the basic properties of metals.
2. What are the standard characteristics of mechanical properties evaluated strength
Metals and alloys? How are these characteristics determined?
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 4.8% C. What is the structure of this
Alloy at room temperature and how such an alloy is called?
4. Using the iron-cementite state diagram, set the temperature of the full and
Incomplete annealing and normalization for steel 20, Describe these thermal regimes
And describe the structure and properties of steel.
5. 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 specific mode for any tool steel.
