12. Testing and Evaluation of Aluminum

Try these first

1. 1.

   What does tensile testing evaluate?

   Hint

   Think about what happens when you pull on a material.

2. 2.

   What is the main purpose of hardness testing?

   Hint

   Consider how resistant a metal is to scratches.

3. 3.

   What is the primary purpose of tensile testing?

   • To determine toughness
   • To measure yield strength and elongation
   • To assess corrosion resistance

   Hint

   Think about how tension affects materials.

4. 4.

   True or False: The salt spray test is used to evaluate the hardness of aluminum.

   • True
   • False

   Hint

   Consider what property the salt spray test is actually assessing.

5. 5.

   You are tasked with designing a new aluminum product for a cold climate. Outline a testing plan focusing on impact resistance and explain your rationale.

   Hint

   Consider the impact of cold on materials.

6. 6.

   Analyzing a failure incident in an aluminum structure, you discovered fatigue was a key factor. Discuss the testing method and how you would gather data on cyclical loads.

   Hint

   Think about how repeated stress affects structures.
