Describe the application and identify all of the key

Question

Note: There are two assignment submission dates, with the first part of the assignment due in week 4 so that students can get feedback in time before submission of the second part.

Many technological developments depend on advancements in materials research. This is particularly the case in applications that require materials to withstand increasingly higher loads and temperatures. For instance the speeds of aircraft are often limited by the creep resistance of materials used for the turbine blades in the engines. While there are many handbooks and databases available that contain descriptions and properties of commonly used materials, there are many newly developed materials that are only contained in research literature. It is important for engineers working in leading edge applications to keep on top of current research to determine whether there are any developments they can exploit.

Assignment: Locate relevant information and submit a research review report for BOTH of the two applications below that contain the following information:

• Describe the application and identify ALL of the key mechanical property requirements of the material in the application?

• What are the important failure mechanisms that MUST be considered in material selection for this application?

• Choose three different commonly used materials for this application and describe the EXACT composition and microstructure of each material (to do this you will need to choose a specific grade of each commonly used material).

• Explain how the microstructure of your three commonly used material grades gives the necessary properties to meet the key mechanical property requirements that you identified.

• Describe one example of a surface engineering approach (coating or treatment) used in this application to improve the properties or assist in preventing failure.

• Identify one NEW material using scientific journal literature that is not widely used at present for this application, but is currently being researched for such. Describe the microstructure of the material and clearly explain why it may potentially be an improvement over current materials.

Answer 1

On the base of the statement illustrated in the assignment, please write answers for the following questions by using proper citations in accordance with MLA style of writing. 1) Illustrate the application and recognize all of the main mechanical property requirements of the material in the application? 2) Describe the significant failure methods which should be considered in material selection for this application? 3) Select three different generally used materials for this application and explain the precise composition and microstructure of each material. 4) Describe how the microstructure of your three generally used material grades provides the necessary properties to meet up the main mechanical property needs that you recognized. 5) Illustrate one illustration of a surface engineering approach employed in this application to enhance the properties or assist in preventing the failure.
