High-Speed Infrared Imaging System for Advanced Metals Processing
Abstract
A high-speed infrared (IR) imaging system with appropriate microscope optics has been acquired and calibrated for radiation and temperature measurements in deformation processing and material removal processes. The imaging system has been incorporated into a plane strain deformation process system for metals, enabling systematic measurement of temperature fields in the process zone. Concurrent characterization of strain and strain rate fields in the process zone using high-speed visible imaging coupled with Particle Image Velocimetry; and energy and friction using force measurements is feasible in this 2-D process system. Some measurements planned in the near future on the Purdue metals processing test bed are described. When fully implemented in the coming months, the combination of measurements will provide unprecedented insight into microstructure and crystallographic texture development in metals processing and wear, and of the interactive effects of strain, strain rate and temperature on microstructure, texture, and flow instabilities.
