摘要：

We have designed an experiment for measuring temperatures accompanying the formation of bands of intense plastic strain. Shear bands intersecting the specimen surface were produced in machining chips of 4340 steel and 2014-T6 aluminum by orthogonal cutting using a lathe. An infrared microscope was then focused on the chip near the cutting tool to record temperature variations as shear bands swept through the focal area. We report preliminary estimates of temperatures, strains, and strain rates.
