Abstract
A newly developed dilute magnesium alloy, Mg-0.27Al-0.13Ca-0.21Mn (at.%), shows extraordinary high-speed extrudability of a die-exit speed of 60 m/min. Subsequent artificial aging at 200 °C (T5) enhanced the proof stress from 170 MPa to 207 MPa due to the precipitation of Guinier Preston (G.P.) zones and weakened basal texture while keeping good ductility of 12.5%. High-speed extrusion reduces the processing cost, so the dilute Mg-Al-Ca-Mn alloy could be an industrially viable low-cost medium strength structural material.
