摘要：
Deformation behavior was investigated in detail from cold extrusion and upsetting tests on medium carbon steel. A new "cold forging after quenching and tempering" (CFAQT) process was proposed. Compared with conventional processes, including annealing before cold forging, plus quenching and tempering after forging, the CFAQT process could shorten the process chain and avoid subsequent heat treatment distortion with clear energy-saving and cost-reduction benefits. The CFAQT process was applied successfully in the mass production of a lock set for industrial automobile wheels and in laboratory spline extrusions.
