Riveted joints – Material choice for rivets\nAre rivets generally manufactured from ductile materials to permit upsetting and reliable formation of the head during riveting?

Introduction / Context:
Riveted joints rely on forming heads by deforming the rivet shank. The material of the rivet must withstand plastic deformation without cracking, ensuring a tight joint and adequate shear/tension capacity.

Given Data / Assumptions:

• Common practice in structural and boiler riveting.
• Hot and cold riveting both used depending on application.

Concept / Approach:
Ductile materials such as mild steel, wrought iron, aluminum, or copper are preferred because they can be upset to form the head and fill the hole, improving load transfer and minimizing stress concentrations.

Step-by-Step Explanation:
During riveting, the shank is inserted and a head is formed by plastic deformation.Ductility prevents brittle fracture during upsetting and service vibrations.Common specifications call for rivet materials with adequate elongation and toughness.

Verification / Alternative check:
Standards and handbooks list typical rivet materials (e.g., low-carbon steels and nonferrous ductile alloys), confirming the practice.

Why Other Options Are Wrong:
Limiting ductility to only hot or only cold riveting is incorrect; both benefit from ductile rivets. Plate material choice does not negate the need for rivet ductility.

Common Pitfalls:
Using overly hard or brittle fasteners can lead to cracking during heading or service, compromising joint integrity.

Final Answer:
Yes
