Abstract
In this study, 2117 aluminum alloy rivets of large diameter are produced and investigated on the properties of strength of them. Extruded round bars are used for the rivets of 22 mm in nominal diameter. First, the forming and heat treatment conditions not so as to generate large grains in the section of the rivets are examined. Next, it is shown that by pressing under cold condition the end of the shank of the rivets into the flat head of 32 mm in diameter and 10 mm in height, the hole of 22.8 mm in diameter is full of the rivet. The static loading and fatigue tests for the joints fabricated by the developed rivets provide the shear strength and the fatigue strength in shear of the rivets.
