AA2024-CNTs composites by milling process after T6-temper condition

► By Milling process can be produced Al-CNT composites. ► CNTs keep their morphology after milling process, are well dispersed into Al matrix and have an important effect over mechanical properties. ► The crystallization of Al4C3 from the reaction between Al and CNTs is obtained. ► Co-existence of CNTs, Al4C3 and Al-Cu is observed after aging heat treatment.
