Cite two examples of secondary bonding in materials and state its important properties (one for each example).
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
Define Pilling-Bedworth ratio. State its importance in evaluating the oxidative corrosion propensity of various metals/metal oxides.
Discuss the bonding character and properties relationship of materials with suitable examples.
Identify 3 types of crystal defects in solids (one point, one linear, and one planar) and suggest for each of these one material property that is adversely affected by its presence and one that is improved. Also state what to look for in a crystal that possesses each of these defects.
Draw the differences between edge and screw dislocation. What is grain boundary?
State and explain Gibb’s phase rule. Briefly explain the important phase transformation in steels.
Give four examples of ethylene based long chain polymers and state one industrial application for each of them.
State the differences between thermoplastic and thermosetting polymers. Name the factors influencing the crystallinity of long chain polymers.
Draw the tensile load-elongation curve and the true stress-true strain curve for a ductile material and explain the salient features.
