Can someone please help me to answer the following question completely. PLEASE AND THANK YOU!!!
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?

- You're an engineer working for a land-based gas turbine manufacturer. These turbines are similar to jet engines, but they are used onshore to provide power for power generation and gas compression pipeline applications. Operation of motor a ceramic-based thermal barrier to turbine blades in the first stage turbine to increase its temperature and efficiency suppose you want to apply a coating. By making the necessary associations between process-structure-property-performance describe in detail the following options. a) What do engineers like when trying to design a ceramic coating to be applied to a super alloy metal blade can you face difficulties? b) what properties should be considered when choosing a suitable ceramic material for a coating?arrow_forwardFor simplified processing calculations, glass-bottle shaping temperature can be taken as the softening point (at which n = 107.6 P ), and the subsequent annealing temperature can be taken as the annealing point (at which n = 1013.4 P ). If the glass-bottle processing sequence involves a shaping temperature of 690 °C for a glass with an activation energy for viscous deformation of 440 kJ/mol , calculate the appropriate annealing temperature. Express your answer to three significant digits.arrow_forwardRegarding annealing, choose the right answer (One or more): The actual annealing time must be long enough to allow for any necessary transformation reactions that may occur Annealing can be performed to release internal stresses of the material The main purpose of annealing is to decrease or restore material's ductility Time isn't a significant parameter in annealing process If the rate of temperature change is too great, temperature gradients and internal stresses may be induced that may lead to warping or even crackingarrow_forward
