Zusammenfassung:	The use of high strength alloys in the art of blind riveting or riveting from one side only of a structure is made possible by novel combinations of rivet bodies and pulling stems. Pure titanium and titanium and other alloys are joined together to form the rivet body, while titanium alloys and other metals are joined together to form the pulling stem, by use of an integral joining process such as the friction welding process. With these combinations it is possible to utilize the great advantages of special alloys and other metals from the standpoint of strength at elevated temperatures and still make possible the formation of blind rivet heads. Similarly the fastening or plug section of the pulling stem is made of a different metal from the metal of the pulling section and is provided with a breakneck usual in the art of blind rivets and lockbolts.
