1. Figure 1 shows copper-nickel piping on a marine chemical tanker. As an inspection engineer, one day you were called to inspect a corrosion problem that occur on surface of the pipe. From microstructural investigation, you find out that the corrosion problem is caused by composition variation across the grain as shown in 2. Using phase diagram given, rationalise this microstructure. Your explanation should include why there are two shades of grey colour in the microstructure and what are their compositions? You are free to choose which ever copper-nickel system (example 80% Cu – 20% Ni) you like from the phase diagram.

Material science Assuming this system forms a laminar type eutectic, determine the volume proportion of phases for an equilibrium solidified 50% Pb alloy. Sketch the expected microstructure.
This is the microstructure of astm a 128 a high magnesease steel. This microstructure was taken after etching the samples. After etching why did it turn the microstructure colors. What can be determined when looking at the microstructure of this sample
If the carbon concentration of a plain carbon steel is 1.0%, and it is cooled fairly slowly (i.e. not quenched) from a liquid melt to room temperature, will the room temperature microstructure be 100% pearlite? If not, what phase will the “non- pearlite” grains consist of?
