Abstract

A new group of Frank-Kasper phases has been observed in Al Li-Cu-Mg alloys using high resolution electron microscopy (HREM). The Y phase, which has a face-centre cubic structure with a = 2.0 nm, occurs in grain boundaries during precipitation heat treatment of supersaturated solid solution. Considerable amount of intrinsic faults, extrinsic faultsand microtwins were observed in the Y phase. A new domain denominatedas D intergrowth with Y phase along {111} planes has been found. By combination of Y phase and D domain, new domains can be constructed.
