Why must rivets of a 2017 aluminum alloy be refrigerated before they are used?

Short Answer

Expert verified
Answer: Refrigerating rivets made of 2017 aluminum alloy before use is necessary to maintain their ductile properties during the riveting process. This prevents premature hardening, ensuring a stronger bond and enhancing the fatigue resistance and overall strength of the final structure.

Step by step solution

01

Understanding 2017 Aluminum Alloy

2017 Aluminum Alloy is an age-hardening alloy, which means that its strength and hardness can be increased by applying heat treatment followed by a controlled cooling process. The alloy consists of copper, magnesium, and silicon as the main alloying elements, giving it high strength, good fatigue resistance, and excellent machinability.
02

Importance of Refrigeration

Refrigeration is a controlled cooling process that slows down the natural aging process of the alloy. Refrigerating the rivets before usage prevents the premature hardening of the rivets, which would make them brittle and more likely to break during the riveting process.
03

Riveting with 2017 Aluminum Alloy

When the refrigerated rivets are used, they are still in their relatively soft and ductile state. They are inserted into the pre-drilled holes and then heated during the riveting process, which causes them to expand and fill any gaps, creating a strong mechanical bond. After riveting, the rivets cool down and undergo the age-hardening process, increasing their strength and further securing the joint.
04

Conclusion

Thus, it is necessary to refrigerate the rivets made of 2017 aluminum alloy before use in order to maintain their ductile properties during the riveting process. This ensures a stronger bond and enhances the fatigue resistance and overall strength of the final structure.
