摘要

摘要--对超声波铆接的研究表明，振动可显著降低铆接力并改变铆钉的变形特性。首先，铆钉柄发生镦粗，铆钉与安装孔之间的间隙被变形金属填满，然后形成闭合头。由超声变形 D18 合金铆钉形成的接合处的剪切力大大增加。

Deformation of a Rivet under Ultrasonic Vibrations

Abstract—The research on ultrasonic riveting has revealed that the application of vibrations enables a significant decrease in the riveting force and changes the deformation characteristics of a rivet. Initially, a rivet shank undergoes upsetting, and the gap between the rivet and the installation hole is filled with the deformed metal, and a closing head then forms. The joints formed by ultrasound-deformed D18 alloy rivets exhibit a considerable increase in the shear force.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
