Abstract

By measurement of physical properties and microscopic examination it was found that the phase Al4Ca undergoes a martensitic transformation with Ms≃130° C. The low temperature structure is monoclinic, a=0.6158 nm, b=0.6175 nm, c=1.118 nm, β=88.9°. The Dl3 structure ascribed to Al4Ca hitherto is valid only above Ms. Orientation relationships indicate that the transformation proceeds by a shear of 1.1° on (1 1 0) planes of the Dl3 structure.
