Abstract

Creep of three chill cast alloys based on the composition Mg-2.5RE-0.35Zn-0.3Mn-0.03Zr:(wt.%) with partial or complete substitution of Nd for Ce mischmetal has been investigated for the stress range 50–90 MPa and temperature range 150-240°C. The Nd substitution reduces the creep rate by factors as high as 8 for the conditions studied and stress to produce 0.1 % strain in 100 h matches reported results for A380 aluminium alloy at temperatures near 200 °C. The possible origins of this improvement in performance are discussed.
