Microstructure Property Relationships If you had 2 mm thick

Microstructure Property Relationships If you had 2 mm thick sheets/sections of: (i) a glassy thermoplastic polymer (ii) a semicrystalline thermoplastic polymer (iii) a fine grained polycrystalline oxide ceramic (iv) a large grained pure aluminum (v) a precipitation hardened stainless steel Which two materials would you expect to exhibit measurable ductility? Which two materials would you expect to potentially be transparent in visible light? Which two materials would you expect to have the largest yield, fracture or flexural strength? List two materials where you could alter the microstructure and properties through annealing.

Solution

Ans:

A: among these material semi crystalline thermoplastic material and large grained pure aluminum have less brittleness. So these two can exhibits measurable ductility.

B: polycrystal oxide ceramic and glassy thermoplastic more transparent than others.

C: which have more tensile strenght have more yield strength. i,e. Semi crystal thermoplastic and aluminium.

D: annealing process used for hardened material to increase machinability. So hard materials like ceramics and stainless steel can change their microstructure properties.
