Q$2$ You are tasked with manufacturing a component using powder metallurgy $(\frac{P}{M})$ of aluminum alloys for aerospace applications.

Processing Steps: Describe each step involved in the $\frac{P}{M}$ processing route for aluminum alloys.

Challenge of Aluminum Oxide Formation: Explain why aluminum powder processing is particularly challenging in comparison to steel powders, focusing on oxide formation. Suggest strategies to mitigate this challenge.

Case Study Reflection: Research a real$-$world application of powder metallurgy in non$-$ferrous alloys $($preferably in aerospace or automotive industries$).$ Provide details about the material used, the component produced, and why $\frac{P}{M}$ was selected as the processing route.

Include at least one diagram to support your explanation. Please be careful to explanation one diagram and must at least $2$ references.
