Prepare a chart on the types of engineering materials based on nature and major areas of applications. Cite examples for each of them.
Explain macro, micro and sub structures of materials. Name some techniques by which these strictures are analyzed and characterized.
Name the constituents of the following materials with percentage distribution: Chromel, Brass, Alumel
Explain the mechanism of creep. Also discuss about the importance of creep resistant materials.
Discuss with examples general types of corrosion and their preventive measures.
Draw the differences between edge and screw dislocation. What is grain boundary?
What are the degrees of freedom of a system of two components when the number of phases is one, two, three, and so on?
State and explain Gibb’s phase rule. Briefly explain the important phase transformation in steels.
Cite examples of some allotropes of carbon other than graphite and diamond (any two). State their important structural characteristics.
Stating the condition for the spontaneous occurrence of a phase transformation, discuss about the progressive transformation of a liquid to solid crystals by nucleation and growth with an illustration.
Define Fermi energy level. How does the electron distribution change at Fermi level when temperature is 0 K and above 0 K.
Draw the tensile load-elongation curve and the true stress-true strain curve for a ductile material and explain the salient features.
Define Pilling-Bedworth ratio. State its importance in evaluating the oxidative corrosion propensity of various metals/metal oxides.
