Recently, Friction stir consolidation (FSC) is a solid-state manufacturing and recycling process for metal scrap, hence, becoming much important side to convert the metal scrap into finish or semi-finished products. In contrast with the conventional process or re-melting process, the FSC advantage that lower metal waste, environmentally friendly and low cost. In This research, investigated the feasibility to produce a fully dense cylindrical billet from milling machine chips of aluminium alloy type (AA2024-T3) by using an FSC process, the chips plunged onto a hollow cylindrical die by a rotating tool. The chips softening due to the friction heat generation and subjected to the dynamic recrystallization DRX and high plastic deformation. The process was done with different values of rotation speed tool, plunging depth of the tool and preheating time. A 20 mm diameter coherent cylindrical billet with four highs (20, 25, 30, and 35)mm were obtained. The quality of the obtained billets is evaluated through morphological observation.
