Abstract

Imposing large plastic deformation by SPD processes such as ECAP, HPT, ARB etc. in a relatively simple way enables to obtain material with high grain refinement. In result significant change in both strength and plastic properties can be observed. However, this hardening effect is highly thermal sensitive and even small increase in temperature can initiate structure recovery processes. In the following paper thermal stability of aluminum chips (AA1050, AA3103, AA5083) after machining has been examined. By identifying moment of structure recovery optimal conditions for plastic consolidation could be determined.
