Choose one example of an engineering component that is made of steel and requires high hardenability properties. Discuss how the elemental composition of the steel-based material used for your component can be hardened. Your discussion must include the specific composition of the steel, properties, and processing method of the component until it is hardened using a continuous cooling transformation ( CCT ) diagram.
Briefly describe how precipitation hardening happens in Al alloys (how the microstructure evolves as annealing time increases). Why it first forms q” then q’ before q is finally formed? How does the alloy’s strength change during this process? What are the strengthening mechanisms?
An uncold-worked brass specimen of average grain size 0.006 mm has a yield strength of 178 MPa.
