Abstract Americium and curium alloys with palladium and platinum containing up to 20% of actinide were prepared by the coupled reduction technique. The alloys obtained were investigated by X-ray, differential thermal analysis and metallography. Phase diagram sections for Pd−Am, Pd−Cm, Pt−Am and Pt−Cm systems have been constructed. Intermetallics Pt5An (An=243Am,244Cm,249Bk,249Cf), Ir2 249Bk and Rh3 239Bk were obtained as thin layers on the surfaces of metallic substrates. X-ray investigation has shown that Pt5An compounds have hexagonal structures of the Cu5Ca-type, Ir2Bk- cubic lattice of the Cu2Mg-type and Rh3Bk intermetallic has fcc lattice of the Cu3Au-type. The influence of intensive α-decay of transplutonium nuclides on the crystal structure of the intermetallics prepared has been investigated.
