Abstract
Large strain extrusion machining (LSEM), a constrained chip formation process, is examined as a method of severe plastic deformation (SPD) at small deformation rates for production of ultra-fine-grained (UFG) materials. A finite element procedure is developed for prediction of deformation field parameters such as effective strain, strain rate, and their variation across the thickness of the chip for various cutting (extrusion) ratios. The cutting force (extrusion pressure) and hydrostatic pressures within the deformation zone are also analyzed. A consideration of the deformation occurring in chip formation suggests bounds on the extrusion ratios that can be realized. Implications of the results for production of bulk chip samples of controlled geometry and with an UFG microstructure are discussed.
