Development of a Mechanistic Model for Friction Stir Channeling

Abstract

A mechanistic model for the process specific energy as a function of the processing parameters during friction stir channeling (FSC) in AL6061-T6 was developed and investigated. The thermal cycle acting on the surface of the workpiece was measured using an infra red (IR) camera and the peak temperatures were studied as a function of the specific energy. The channel area is plotted against the process specific energy and is analyzed. A relationship between the processing conditions (tool rotational rate, traverse speed, and plunge depth) and the channel area is defined.
