Powder Crystal Data for the High-Temperature Phases Cu4In, Cu9In4(h) and Cu2In(h)

Abstract The high-temperature phases Cu 4 In, Cu 9 In 4 (h) and Cu 2 In(h) cannot be retained by quenching. In contrast to this, splat-cooling specimens of these alloys yielded single phase products. Cell parameters in the range of homogeneity of these phases were measured. Powder crystal data for Cu 4 In(W type), Cu 9 In 4 (h) (Cu 9 Al 4 type) and Cu 2 In(h) (Ni 2 In type) are given.
