The Status and Development of ECAP

Article Preview

Abstract:

ECAP is a large plastic deformation processing technology, ultrafine-grained materials can be prepared using ECAP process. This paper reviews the channel angular extrusion process application in aluminum alloy, copper alloy, magnesium alloy and composite materials and so on. Summarizes the influence of the central angle and mold inside corner radius, processing route, the coefficient of friction , extrusion speed, extrusion temperature, extrusion and steps on the ECAP. Also introduced a more advanced package sets-ECAP and continuous ECAP process.
