The Allocated alloys are
(i) Alloy : Udimet 720
(ii) Technical ceramic : Boron nitride
(iii) Polymer/elastomer : Polycarbonate
| Question 6
Ta) Explain the microstructural changes that your allocated alloy exhibits during age
Thardening. You should use a sketch the microstructure of your material (i) held for 30
I minutes at the solution temperature, (ii) after, subsequently, cooling rapidly from the
|solution temperature to room temperature, (ii) after, subsequently, holding at the
commercial aging temperature for the prescribed time, to support your explanation.
I b) Compare and contrast how precipitates (i) increase the yield strength of some alloys
at room temperature, and (i) lower the creep rate of some alloys at elevated
temperature.
Ic) Your allocated alloy is strengthened by intermetallic precipitates that grow during
aging. By both defining an intermetallic and detailing those found in your alloy, explain
| why they are so effective at strengthening your material.
A processing technique called Equal Channel Angular Pressing (ECAP) has been used for many metals and alloys to impose severe plastic deformation, and therefore create extreme dislocation densities. However, the primary purpose of ECAP is not to create high strength by severe work hardening. What is the main reason to perform ECAP processing, and why is the technique particularly attractive for this purpose?
How does the undercooling of a metallic
material during heat treatment relate to it's
mechanical properties?
