Stable Al—Ni—Rh decagonal phase

Decagonal (D) phase was found to be stable at 1100 °C in a small compositional range around Al_70.5Ni_15.5Rh₁₄ which overlaps with the overall range of the D-phase in Al—Ni—Co. The Al—Ni—Rh D-phase exhibits the basic tenfold diffraction pattern and the basic periodicity of about 0.4 nm with diffuse diffraction layers corresponding to the double periodicity. At 1100 °C it co exists with the ternary extensions of binary Al₃Rh and C—Al₅Rh₂ and with the liquid, at 1000 °C no D-phase was observed.
