[HTML][HTML] Microstructure and catalytic properties of rapidly solidified Al-28.5 at% Fe and Al-28.5 at% Co alloys applied for selective hydrogenation of phenylacetylene
Abstract The Al 71.5 Fe 28.5 and Al 71.5 Co 28.5 (at%) melt-spun alloys were examined in
terms of microstructure evolution and catalytic response in the semihydrogenation reaction
of phenylacetylene to styrene. In the as-spun state ribbons showed a single-phase
composition. The Al 71.5 Co 28.5 alloy contained columnar grains of a metastable
decagonal quasicrystal, which transformed into hexagonal Al 5 Co 2 and monoclinic Al 3 Co
phases after heat treatment at 900° C. The Al 71.5 Fe 28.5 ribbon had an ordered …
