1. What are the substitutional solid solutions and implementation? Give examples.
2. How and why in the cold plastic deformation properties of metals change?
3. Draw a diagram of the state of the iron - iron carbide indicate structural components in all areas of the diagram, describe the transformation and build the cooling curve (using the phase rule) for the alloy containing 0.8% C. What is the structure of the alloy at room temperature, such as the alloy called?
4. Using a phase diagram of the iron - iron carbide and plotting the hardness of the tempering temperature assign mode heat treatment (quenching temperature, the cooling medium and tempering temperature) of steel 50 which must have a hardness of 230 ... 250 HB. Describe the microstructure and properties of the steel 50 after the heat treatment.
5. Steel 40 was subjected to quenching from temperatures of 760 and 840 ° C. Using the phase diagram of iron, cement, select the heating temperature selected and describe the transformation that occurred in the two modes of quenching. Which mode should be preferred and why?
