Microstructure of Various Steels (hypoeutectoid, eutectoid and hypereutectoid)
1. What is the primary microstructure in hypoeutectoid steels with less than 0.8 wt% C?
2. What transformation occurs when autenitic phase transforms into laminar structure of ferrite and cementite (called pearlite)?
3. How does quenching affect the microstructure of steel with 0.7 wt% C?
4. What type of crystal structure does martensite have?
5.Which element is responsible for the stainless properties of stainless steel?
6. What type of oxide film forms on the surface of stainless steel, making it corrosion-resistant?
