Abstract

Thermal effects play a central role in determining the microstructure and mechanical properties during deformation processing. Unlike in directed energy processes, such as laser cladding or welding, prediction of temperature fields in deformation processing requires consideration of multiscale heat generation and heat transfer phenomena between the tool, workpiece, and surrounding lubricant. In this work, we develop an analytical method to evaluate the temperature rise in a workpiece as it interacts simultaneously with a tool and lubricant. The method operates on multiple length scales and partitions the generated heat using suitable temperature-matching principles. We demonstrate the utility of the scheme by analyzing two deformation processing operations�surface grinding and friction stir processing�and a problem in four-body wear, and compare the results with infrared thermography measurements. Final temperature predictions match well with experimentally measured values. Given its analytical nature, our scheme enables easy evaluation of parametric effects, thus distinguishing it from commonly used finite element techniques. © 2022, The Minerals, Metals & Materials Society.
