A new intermetallic pentagonal Frank-Kasper phase determined by HREM
Description
A new intermetallic pentagonal Frank-Kasper phase coexisting with the well known μ and Laves phases has been found in precipitates from superalloys. The lattice parameters of the new PF phase, which were determined by means of high-resolution electron microscopy and selected-area electron diffraction, are: monoclinic, space group B2/m, a=20.4, b=11.7, c=4.7 A and γ=112.40. Based on an analysis of the structural units, the atom positions derived from high-resolution images are also given. (orig.)
